It looks very much like the tail wagging the dog. To me it appears as though a tiny segment of the community couldn't muster the discipline to call their deviant definition something else and, after having caused confusion in their own circles (there are variable star people who do use the proper definition of MJD), possibly out of spite, force everbody to abandon a useful concept. This decision to recant is even worse, since most of the community is not going to change what they have been doing for years, acting as if it still is an IAU-blessed unit, while in reality it isn't (speaking of confusion!). There are too many FITS files out with MJD, there is too much software that uses it. The variable star folks will have to face reality and acknowledge that even an IAU decision can't keep the community from using the former IAU-condoned definition of MJD. >>... Most people don't like the idea of a day >>starting at noon except for astronomers .... >Well, most people don't like time tied to Greenwich unless they live near >England.

I rather suspect that the half day offset originated from nautical practice to start the day at noon: that was the moment in the day that all important things happened, with noon sightings of the sun and taking the nautical almanac from the shelf - determining the elevation of the sun at midnight is too problematic. >You are, of course, welcome to continue using MJD *if* you keep your >readers informed of what you mean by it. It's just no longer approved >by the IAU as an astronomical standard. Like Prohibition, it looked >like a good idea at one time, but did not work out well in practice.... Unlike prohibition, it _was_ a good idea ... I'm sure this was pretty much a storm in a teacup. FITS files will continue to carry MJD - perhaps with an extra comment - and most astronomical software will continue to use it. What may need to be stressed, though, is that using MJD (or JD, for that matter) for defining a moment in absolute time requires not only an MJD value that includes a fractional part, but also an indication what time system is being used. The Julian Day is not tied to any particular time system (UTC, TAI, TT, ...), it only provides a formalism for counting calendar days within such a time system. For instance, the epoch 1994.0 (UTC) (January 1, 1994 at 00:00:00 UTC, or MJD=49352.0 (UTC)), is at MJD=49352.000696574074 (TT). Very seldom does one see a time system identified when MJD is given. -- _---------------------Arnold H.

Having pulled back all the info I could from NOST I could find no information on this. Could anyone point me in the right direction please? What I had understood was it was possible to store a raw image and then specify the transformations required (mathematically). When it came to display the image it was a matter of reading the raw image and then applying each of the transformations. Is this really a possible thing to do?

These two ANSI C functions, worldpos() and xypix(), perform forward and reverse WCS computations for 8 types of projective geometries ("-SIN", "-TAN", "-ARC", "-NCP", "-GLS", "-MER", "-AIT" and "-STG"): worldpos() converts from pixel location to RA,Dec xypix() converts from RA,Dec to pixel location where "(RA,Dec)" are more generically (long,lat). These functions are based on the WCS implementation of Classic AIPS, an implementation which has been in production use for more than ten years. See the two memos by Eric Greisen ftp://fits.cv.nrao.edu/fits/documents/wcs/aips27.ps.Z ftp://fits.cv.nrao.edu/fits/documents/wcs/aips46.ps.Z for descriptions of the 8 projective geometries and the algorithms. Footnotes in these two documents describe the differences between these algorithms and the 1993-94 WCS draft proposal (see URL below). In particular, these algorithms support ordinary field rotation, but not skew geometries (CD or PC matrix cases). Also, the MER and AIT algorithms work correctly only for CRVALi=(0,0). Users should note that GLS projections with yref!=0 will behave differently in this code than in the draft WCS proposal. The NCP projection is now obsolete (it is a special case of SIN).

This is a FITS image viewer for Windows which features manipulation of the display (brightness, contrast, pseudo color), zoom and scroll, blinking images for comparison, displaying 3-D images as a "movie", and determining the celestial position and brightness of features in the image. Celestial positions are determined using world coordinate projections (WCS). All defined FITS data types are supported (8, 16, 32 bit integers and 32 and 64 bit IEEE), as are blanked pixels. Two and three dimensional simple FITS images are supported. FITSview runs on Windows 3.1 or later and uses any multicolor (or multiple gray level) display although 256 color displays give the best results. Extensive online documentation is included. FITSview for Windows is available at no cost via anonymous ftp as the two files: ftp://fits.cv.nrao.edu/fits/os-support/ms-windows/fitsv03.txt ftp://fits.cv.nrao.edu/fits/os-support/ms-windows/fitsv03.zip Installation is described in file fitsv03.txt.

These classes deal with all the usual FITS types - Primary Array, Image Extension, Binary Tables, ASCII tables, and Random Groups. It needs to be emphasized that the classes are presently very poorly documented. However, since they are useful we are releasing them on an informal basis. They will be released with improved documentation at a later time. 0. Contacting us Send any bug reports, comments, requests for features, porting notes, etc. to aips2-bugs at nrao.edu. 1. Location The master distribution location is in the directory: ftp://aips2.nrao.edu/pub/aips++/RELEASED/fits/ We anticipate that it will be cached at other FITS repositories. In particular, it is also found at: ftp://fits.cv.nrao.edu/fits/src/ FITS information in general may be found at http://fits.cv.nrao.edu/ 2. Installation The make system used internally to the AIPS++ project is quite involved. A very simple set of makefiles are supplied here. o Retrieve and unpack the distribution o cd aips; make # makes lib/libaips.a - mostly a Complex class o cd FITS; make # makes lib/libfits.a o cd test; make # makes bin/tfits[1-5]; some small test and # sample programs Making the sample programs will also cause template instantiations to be placed in a library for faster linking. It will work "right out of the box" for CFront 3.0.1+ based compilers under Solaris 2. The code also compiles under AIX with IBM's xlC compiler, and under IRIX with the SGI native compiler. It has been compiled on PC's with Borland in the past, but we haven't done this recently. We are very interested in any experience you might have porting these classes, and will endeavour to get such changes into the mainline code. "make distclean" from the top (aips) directory should clean out all generated files. 3. Use A more formal release will have better tutorial and reference documentation. Until then, there is some documentation in the headers, particularly hdu.h, and the test programs show by example how to use them. tfits1 - Parse a FITS file tfits2 - Create a primary array and image extension tfits3 - Create a random groups file tfits4 - Create a binary table tfits5 - Convert an ASCII table to a binary table 4. Known bugs and deficiencies o The classes presently do not work from tape drives. o Null values in ASCII tables are not handled. 5. Copyright The code is under the GNU library license. See the file aips/COPYING for details. 6. Version The software in these classes corresponds to AIPS++ internal distribution 4.058 (19OCT94).

The revisions deal with the units for angular measure and celestial coordinates. This draft is being distributed for comments by a new Technical Panel appointed by the NASA/Science Office of Standards and Technology (NOST). Among the responsibilities of this panel is to rectify any errors or oversights in version 1.0 of the NOST Standard. The new Panel is chaired by Dr. Robert J. Hanisch (Space Telescope Science Institute), who chaired the panel that developed version 1.0 of the Definition of FITS. The panel has considered the issue of requirements and recommendations on units for FITS files in response to community comments on the version 1.0 treatment of this area. Draft revisions are being released to the community for review and comments. The Technical Panel will review these comments. The Panel will either revise the draft revisions to incorporate the substance of a comment or state the reasons for not doing so. The Panel will respond to all comments. All comments must be received by 21 November 1994. When the commmunity review process is complete, the text finally adopted by the Technical Panel will be incorporated in the NOST Definition of FITS, producing version 1.1. Comments should be sent in writing to the NOST Librarian, at the electronic and postal addresses at the end of this announcement. The draft text for units revisions is available by anonymous ftp from nssdca.gsfc.nasa.gov/fits/units_revision.txt or by DECnet copy from NSSDCA::ANON_DIR:[FITS]UNITS_REVISION.TXT.

Evidently, httpd thinks that FITS files are text, probably because they start with an ASCII header. Unfortunately, the documentation for httpd is on http://hoohoo.ncsa.uiuc.edu/ which is (chronically) down. Does anyone know how to tell NCSA's httpd to treat files ending in .fits as binary files? One clue that I have is that there is a file in the "conf" directory called mime.types which contains lines like image/jpeg jpeg jpg jpe Evidently, one is supposed to enter a line in this file with the MIME data type followed by a list of extensions this will apply to. This should be something that will tell the browser on the other end that this is a FITS file, so that if a suitable viewer is available (e.g. SAOIMAGE) then it will pop the file directly into that program. Is there any standard for what that line should be (assuming I'm guessing right)?

In particular, it can be taught how to view FITS images.

(The same mechanisms could be used to email and view FITS images from inside a MIME-capable mail reader such as elm.) First, create a .mime.types file in your home directory containing image/x-fits fits Then, create a .mailcap file in your home directory containing image/x-fits; saoimage %s The next time you start Mosaic it will know what to do with a FITS image found anywhere on the Internet.

I think this is a bad idea, for several reasons. 1. Most of the people I will be passing data to will not have a FITS-viewer, such as saoimage, that they can simply pass the data to. This may reflect the fact that I'm in a different community, solar physics, then the normal "nighttime" astronomical community. If I use "image/x-fits" then the default behavior will be to pass the file to xv, lview or some other similar viewer which will not be able to view a FITS file (at least not unpatched). More useful for my users will be to have Mosaic, etc., automatically copy the file to disk so that it can then be read in and processed by IDL. I know that it's possible to make Mosaic do this, but I want to avoid any possibility of confusion or wasted bandwidth. For simply popping an image up on the screen we plan to provide GIF or JPEG files. 2. Most of our data will not be simple 2D images. There will be a significant subset that will be, but the bulk of the files will be more complex than that. Binary tables will be extensively used. Perhaps a good compromise would be to have two possible MIME types for FITS files: image/x-fits For simple images application/x-fits For more general FITS files William Thompson From fitsbits-request Tue Oct 25 18:38:07 1994 Status: RO X-VM-v5-Data: ([nil nil nil nil nil nil nil nil nil] ["854" "" "25" "October" "1994" "21:42:34" "GMT" "William Thompson" "thompson at orpheus.gsfc.nasa.gov" "<38ju4a$ceg at paperboy.gsfc.nasa.gov>" "23" "Re: Telling httpd that FITS files are binary" "^From:" nil nil "10" "1994102521:42:34" "Telling httpd that FITS files are binary" (number " " mark " William Thompson Oct 25 23/854 " thread-indent "\"Re: Telling httpd that FITS files are binary\"\n") "<38j4v3$498 at paperboy.gsfc.nasa.gov>"] nil) Received: by fits.cv.nrao.edu (4.1/DDN-DLB/1.5) id AA06248; Tue, 25 Oct 94 18:38:07 EDT Return-Path: Message-Id: <38ju4a$ceg at paperboy.gsfc.nasa.gov> Organization: NASA Goddard Space Flight Center -- Greenbelt, Maryland USA Path: saips.cv.nrao.edu!hearst.acc.Virginia.EDU!concert!gatech!howland.reston.ans.net!europa.eng.gtefsd.com!news.umbc.edu!haven.umd.edu!ames!newsfeed.gsfc.nasa.gov!orpheus.gsfc.nasa.gov!thompson References: <38j4v3$498 at paperboy.gsfc.nasa.gov> From: thompson at orpheus.gsfc.nasa.gov (William Thompson) Sender: fitsbits-request at fits.CV.NRAO.EDU To: fitsbits at fits.CV.NRAO.EDU Subject: Re: Telling httpd that FITS files are binary Date: 25 Oct 1994 21:42:34 GMT thompson at orpheus.gsfc.nasa.gov (William Thompson) writes: >Perhaps a good compromise would be to have two possible MIME types for FITS >files: > image/x-fits For simple images > application/x-fits For more general FITS files I looked over again the mime.types file that came with NCSA's httpd and noticed that there are entries for HDF and netCDF files which read application/x-hdf hdf application/x-netcdf nc cdf Since I see FITS files as more closely related, in terms of the goals it's trying to accomplish, to HDF and netCDF than it is to GIF and JPEG, I see this as another argument that it should be "application/x-fits".

When I accepted the role of Chair of the IAU FITS Working Group on August 23 at Den Haag, I presented a proposed agenda for the current triennium. The fifth item on my list was: \item Register FITS with the Internet (IANA) as a MIME data type. I added this item to my list because I believed that we would soon find a need to use MIME type codes for transmission of FITS files. This current thread of discussion shows that my prediction was correct! The FITS community should continue this discussion for a while, and should continue experimenting with type codes. When our ideas have stabilized, somebody can formulate a specific proposal to register one or more codes for FITS. The proposal should be posted in sci.astro.fits for community review. Finally, the proposed application to IANA will be considered by the IAU FITS Working Group, and they can authorize it by a formal vote. -- Donald C.

Date: 27 Oct 1994 06:47:48 GMT Hi all, I am trying to find get information about the single dish fits format. I need this to store spectral line data from a radio telescope. Currently we are using out own format using standard FITS. We want to change this because of some problems we are having and to be a bit more standard. I have looked through the NRAO ftp/html/wais site but can find very little single dish fits information. (Namely a sample file from unipops and a collection of news/email discussing single dish fits, but it is dated 89/90. Can anyone point me in the right direction. I want to be able to write in the single dish format as well as read. Any FORTRAN code would be welcome. Any ftp or html sites would be a good help. Cheers Chris Phillips
