Date: Sat, 2 Apr 1994 15:27:34 GMT Regarding 16 bit unsigned integers in ST6/SpectraSource FITS images: 1. In both the ST-6 and SpectraSource software, one has the ability to subtract 32767 from all pixels before writing the FITS image. This 'fixes' the wrap around problem for pixels with counts >32767, although the pixels then have a range from -32767 tro + 32767. 2. An alternate approach for the ST-6 is to use Compuscope's Personal Observatory software to control the ST-6. This is *much* better than SBIG's software in any case, and does the 32767 subtraction automatically. Unfortunately it doesn't support the 'track and accumulate' feature, but it does have filter wheel control built in. 3. We have written our own camera control software for the HPC-1 which complies with the [current] FITS standard. It is part of a complete telescope/camera robotic system and is written in C for a Unix/Motif platform running on a PC with an ISA bus. Anyone interested in more details can contact me directly.

Here is a brief description of the FTOOLS package that is available from legacy.gsfc.nasa.gov in the /software/ftools/release subdirectory. Currently, version 2.8 of FTOOLS is available, but version 2.9 is expected to be released by the end of April. FTOOLS consists of more than 100 individual programs that perform various operations on FITS format files. The programs can be run standalone, or as integrated tasks under IRAF. Here is a list of some of the more general FTOOLS programs (in version 2.9). (There are also many other FTOOLS programs that are more specifically useful for high-energy astrophysics missions).

Hi Andy, I think what you're after is SAOimage, although patches to XV exist to allow it to read a FITS disk image. You can ftp the source for SAOimage from iraf.noao.edu (140.252.1.1) as iraf.old/saoimage.tar.Z, documentation is available in the files saoimage.ps.Z and saoman.ps.Z. Lastly a pre- compiled sparc binary is in the contrib directory as saoimage.sparc. Any questions or problems with it should be sent to iraf at noao.edu.

So do the Big Bear Solar Observatory FITS files (available by anonymous FTP to suncub.bbso.caltech.edu), on many FITS viewers. We write our data in the order it comes off the chip (or digitizer); i.e. left to right and top to bottom (the first value is in the upper left), to avoid having to invert the array. "Top" and "left" are somewhat arbitrary with respect to the sun as well, depending on the optical configuration. (It's all explained in the 000README.NOW file on our image archive.) Many FITS viewers display left to right and bottom to top (the first value is in the lower left). Is this behaviour specified by the standard (I couldn't find it, but I have an older copy)? SAOimage accepts a command line argument specifying where the first pixel goes (and thus the axis directions). -G.

The standard documents do not specify anything about the orientation of the display of a FITS image; they merely describe how it shall be stored. Personally, I find it somewhat hard to understand why IRAF chose to display pixel 1,1 at the lower left. Many CCD detectors plainly originated as video devices intended to be used to display on a standard video screen where the origin is at the upper left. This is the standard video coordinate system and it is also the system adopted by the writers of the X Window System. It seems only fair to acknowledge the roots of the technology, especially when dealing with the original hardware which had little extra power to do things such as re-rasterize the image. (Lick uses the standard video coordinate system.) The draft "Representations of Celestial Coordinates in FITS" paper by E. Greisen and M. Calabretta recommends that FITS images be displayed with 1,1 in the lower left corner, though it leaves open the possibility that a (powerful enough) display system should re-orient as desired. We probably need to remember that this is akin to the other odd things about astronomy: FITS arrays begin with 1 not 0, temperature increases to the left in the HR diagram, larger magnitude is a fainter star, the longitude of the sub-solar point decreases with time, etc. All these things simply have to be drilled into the introductory classes and written into the specs which control how the software will be written. Otherwise we will all be off-by-one and flipped upside down. :-) -- -- -- -- -- -+- -- -- -- -- -- -- -- -+- -- -- -- -- -- Steve Allen | See us on the World Wide Web | sla at lick.ucsc.edu UCO/Lick Observatory | The URL is ftp://lick.ucsc.edu/ | +1 408 459 3046 Santa Cruz, CA 95064 | pub/outgoing/sla/sms.html | Seabright Morris From fitsbits-request Wed Apr 13 20:24:04 1994 Status: RO X-VM-v5-Data: ([nil nil nil nil nil nil nil nil nil] ["1275" "Wed" "13" "April" "1994" "22:10:03" "GMT" "Doug Tody" "tody at lepus.tuc.noao.edu" "<1994Apr13.221003.8687 at noao.edu>" "27" "Re: Upside Down (was Re: No ST-6 FITS images ?)"

I suspect this predates IRAF, however lower left is appealing to people with a mathematical background, where the origin (of the positive XY quadrant) is always in the lower left. It is the graphics folks that have it backward. The new Ximtool display server has buttons allowing the displayed image to be easily flipped in either axis, so this should soon become a non-issue. As Steve points out, FITS itself does not care how the image is displayed. - Doug -- Doug Tody National Optical Astronomy Observatories IRAF project tody at noao.edu P.O.

Pet peeve time: (One of my pet peeves about the FITS standard is that the word-order is opposite that of my VAX machines, forcing me to byte-swap before I write as it is. I realize I could probably do the image-invert in the same lopp, but it gets increasingly complicated.) (Or maybe that's one of my pet peeves about VAX machines.) :-) (Maybe the standard ought to specify THREE things about the data: number of bits/pixel, signed/unsigned, and byte order. But then, the standard is more than complicated enough, thanks to the binary tables, etc. It could be done IF it had stayed an IMAGE standard.) (And I'm annoyed that I'll have to store the 10-bit CCD data from our new camera as 16-bit; I can't just say BITPIX=10, squeeze out the zero bits, and get an instant 40% compression.) :-) >Personally, I find it somewhat hard to understand why IRAF chose to display >pixel 1,1 at the lower left.

I believe I can guess why IRAF and others chose the lower left corner: because a standard coordinate grid has its origin in the lower left of the positive axes, and increases up and to the right. So why don't chips read from the lower left (and video scan from the lower left, etc.?) Because the English language is written and read from the upper left, rightward and downward, perhaps? >We probably need to remember that this is akin to the other odd things about >astronomy: FITS arrays begin with 1 not 0, temperature increases to >the left in the HR diagram, larger magnitude is a fainter star, the >longitude of the sub-solar point decreases with time, etc. Did astronomers decide that as long as they got one thing backward, they might as well get EVERYTHING backward in the hopes it would cancel? :-) -G.

(Lick uses >the standard video coordinate system.) Why should FITS be tied to a specific detector such as a CCD? There are a lot of other ways to gather data. The FITS standard does allow for the inclusion of information relating to the orientation of the data. Both the World Coordinate System and the older CRPIXn, CRVALn, CDELTn system document how the data relates to real world coordinates. This may or may not be the same as the way the data falls onto the detector, depending on the optical system used to feed it. When analyzing data, I find it convenient that images are displayed with the origin at the lower left, because contour plots are done the same way. This makes it easy to combine images and graphics. I don't use IRAF myself--I use IDL which evidently does it the same way as IRAF. (IDL does allow one to display images with the origin at the upper left if desired, by manipulating a global variable.)

It is the graphics folks that have it backward. Monitors conventionally scan from left-to-right and from top-to-bottom. In the days of devices that were accessed as frame buffers (such as the old IIS Model 70s) it was convenient to use the same data layout so that data would be read sequentially and fed to the monitor in the order that it was needed. In this case placing the origin at the top left was a natural choice and this has carried over to less-hardware oriented graphics interfaces that still work at the pixel level (such as X11). On the other hand, truly hardware-independent graphics interfaces (such as GKS, PEX and PostScript) generally use a coordinate system with the origin at the bottom left-hand corner, corresponding to the normal convention used on paper.

The "portable bitmap toolkit" known as PBMPlus is included in the "contributed" portion of X11R5. PBMPlus was developed by Jef Poskanzer with help by many others. Unfortunately, Jef no longer has time to work on it. PBMPlus has been extended by others (not me) to become NetPBM. I'm appending the announcement. I hope this helps. Selden seb at lns62.lns.cornell.edu ================================================================ N E T P B M Release 1 March 1994 Netpbm is a toolkit for conversion of images between a variety of different formats, as well as to allow a few basic image operations. The package is intended to be portable to many platforms. It has been tested under UNIX (BSD and SYSV, e.g. SGI, Sun4, Sun386i, DEC and Apollo DN 3500), VMS and AmigaDOS. There are also compiler directives in it for MS-DOS. You'll find the latest release of Netpbm at the following sites: * wuarchive.wustl.edu (128.252.135.4), directory /graphics/graphics/packages/NetPBM * ikaros.fysik4.kth.se (130.237.35.2), directory /pub/netpbm. * ftp.informatik.uni-oldenburg.de (134.106.1.9). This site also carries binaries for the Amiga. * peipa.essex.ac.uk (155.245.115.161), directory ipa/src/manip * ftp.rahul.net (192.160.13.1), directory /pub/davidsen/source * ftp.cs.ubc.ca, directory /ftp/archive/netpbm * ftp.x.org, directory /contrib You'll also find a mirror site at the BBS: * sixhub.tmr.com in the "source" area. Netpbm is based on the widely spread Pbmplus package (release: 10 Dec 91). On top of that, a lot of improvements and additions have been made. After the latest release of Pbmplus, a lot of additional filters have been circulating on the net. The aim of Netpbm was, to collect these and to turn them into a package. This work has been performed by a group of program- mers all over the world. If *you* have some code to add, please contact us, and we will incorporate it. There is a mailing list for discussions about Netpbm. You post a message to the list by writing to "netpbm at fysik4.kth.se". If you want to be on the list, please contact the list administrator, "oliver at fysik4.kth.se". Please note, that this is not an official Pbmplus release. The code in this release is merely a collection of code from various sources around the world. Not all of the new code parts follow the high standard of programming of Pbmplus. We have tried to make the code portable to as many systems as possible, but we haven't cleaned up all routines. We hope that this release will help the many users of Pbmplus to upgrade their code all in one piece, instead of having to hunt down different code fragments at different sites around the world. We also hope, that our effort will help the author of Pbmplus, Jef Poskanzer, to make a new official release soon.

I don't know of anyone who has done this yet, though I have heard from a couple of people who are working on it. One is Pete Sauerbrei at the University of Iowa (pjs at astro.physics.uiowa.edu), but maybe you're asking because he is having problems! The other is Denis Priou (priou at mesioa.obspm.fr), who is working on porting the decompression software for the Digitized Sky Survey to DOS. There seem to be serious problems with memory management under DOS. I've never done any DOS programming, but if it is not possible to effectively read the whole image into memory then the program would have to be modified to compress the image in blocks (with resulting changes in the output file formats.) We have effectively done this for the compression of the STScI Digitized Sky Survey (scanned version of the POSS & ESO plates). There the images are 14000x14000; we compress them in blocks of 500x500. I have not written code for the general problem of compressing huge images in blocks, though. If anyone has already done the port to DOS (or has tried and failed), I would be interested in hearing about it too.

This allows it to read and write fits files, and hence convert to/from GIF,PM,PBM,X11 bitmap, Sun rasterfile, BMP, PostScript, IRIS, JPEG and TIFF files. It can display files with NAXIS being 2 or 3; for 3-dimensional fits files the dataset is divided into NAXIS3 sub-images. All BITPIX values are supported. HISTORY and COMMENT keywords will be presevered when converting to/from fits files if the source/destination format supports commentary data. To my knowledge the code has been used under Vax VMS 5.5, Univel SVR4.2, hp-ux 8.07, SunOs 4 and SunOs 5. The patches to xv can be fetched by anonymous ftp from the file pub/software/xv-patches/FITS-v2.tar.Z at ftp-hst.ast.cam.ac.uk. It should be unpacked in the xv-3.00a source directory. David Robinson.
