The above does not specify whether an ASCII table or a binary table is intended. The proposed structure appears to fit most naturally in an extension of type BINTABLE, where the array could appear as a single field. There has been some talk, particularly within the single dish community, of conventions for use of the terms CRVALn, CRPIXn and CDELTn to describe an array contained in one field of a binary table.

IMDISP is an interactive image processing program that runs on an IBM PC computer. It was written to be used with the Voyager and Magellan images which are available on CD-ROM. IMDISP has appeared on the GRIPS CDROM (version 4.4) and the GRIPS 2 CDROM (version 5.6), and is currently distributed with the planetary images CDROMs. IMDISP 7.9 is available via anonymous ftp at ames.arc.nasa.gov [128.102.18.3] in a file called imdisp79.zip in the pub/SPACE/SOFTWARE subdirectory. IMDISP79.ZIP consists of the following files: IMDISP.EXE - IMDISP program version 7.9 IMDISP.DOC - User's Guide for IMDISP 7.9 IMDISP.HLP - IMDISP Help file PALETTES.ZIP - Collection of color palettes PAL.BAT - Batch file to display each color palette CYCLE.BAT - Batch file to color cycle each color palette COPIM.EXE - Image copying program CONVERT.EXE - Pixel conversion program The demo files have not changed but have been repackaged into two files of more manageable sizes, IMDISPD1.ZIP and IMDISPD2.ZIP. The demo requires a minimum of a 800x600 graphics display, 3MB of memory, and 3MB of hard disk space. Being one of the programmers for IMDISP, I would appreciate any feedback on IMDISP, including any problems encountered and suggestions for improvement. The features of IMDISP are listed below.

Does your DOS program act like a "black box" i.e. you simply call it with the name of the input and output files? And are you thinking of making your Windows version callable as a DLL? This would help make it accessible to other Windows programs. I (for one) would be happy to receive uuencoded mail when/if you are ready to try it out! Good luck & thanks for your response.

We have a data format that im looking into formatting into a FITS table. Each record (of our data) contains various values and an array. The values are of differing formats but the array is fixed at 126 single precision values representing counts at some wavelength. I had wanted to use CRPIX, CRVAL, and CRDELT to specify the wavelengths for the array but it doesn't apply to any of the other values in the table row other than the array. Is there FITS support for doing this? I can only find references for CRVAL and such in the primary HDU of the FITS files. I couldn't find it for the FITS extensions. By the way, is there any documentation for the extension 'IMAGE' or is it just too obvious to bother. It's rather obvious to me unless im missing somthing subtle.

For instance we also deal with image data that are expressed as lists of pixels in a table, or as a 2-d vector element in a binary table. Along with the image data itself, we also need to provide the usual coordinate system information for images in these different formats (analogous to the CTYPEi, CRPIXi, CRVALi, etc. keywords in a primary array). We have developed a proposal for the FITS coordinate keywords to be used in these different types of images and are posting it here for further comment and discussion. Our local FITS Working Group has provisionally approved this proposal and we will be using it in some of our data sets. The full proposal is available via anonymous ftp from legacy.gsfc.nasa.gov in the documents/fits/ofwg_recomm/ directory. The latex file is called coord_keywords.tex and the corresponding postscript file is called coord_keywords.ps. To just briefly describe the proposal, the following table shows the corresponding keywords to be used for the different types of images.

Although there may have been good reasons for this selection in the past, it is arbitrary, inconsistent, and too restrictive for present day needs. I propose that 16- and 32-bit unsigned integers be recognized, as well. History ------- When the first draft of a FITS convention was worked out, more than two decades ago, the context was that people needed a means to transport radio astronomical images which usually consisted of intensities represented by floating point numbers. It was extremely cumbersome, in those days, to deal with all the various floating point representations that were in use (note, that floating point numbers did not come to FITS until an IEEE standard had been established) and, hence, the obvious solution was to revert to scaled integers; 16-bit integers, that is, since not all computers could handle bigger numbers. The decision whether to use signed or unsigned was not difficult: if one has to scale the number anyway, it does not matter, while the signed integer was more familiar to the Fortran afficionados of those days (as we all were - except for the Algol buffs). One's or two's complement was decided in favor of the latter; I believe that CDC was the only significant manufacturer around at the time that still used the former. When 8-bit integers were admitted to FITS, the motivation was different. The push came, no doubt from people who had to deal with imaging and display devices that effectively used unsigned 8-bit integers, though characters may have provided impetus, too. Notwithstanding the fact that the BYTE data type in most Fortran-77 extensions was a signed integer, it was recognized that that would be a bad choice: the natural device data type was unsigned and insisting on conformance with the other recognized integer data types would have required endless scaling of these numbers. However, these decisions have led to a situation where the choice of recognized integer data types forms an arbitrary and inconsistent collection: some signed, some unsigned, without a clear justification based on current use. The Current Case ---------------- Contrary to the situation of 20 years ago, many of the data transported via FITS are now derived from photon counting instruments that use unsigned integers as their native data type: naturally, since one cannot count fractional photons or negative photons. I strongly urge the various standards organs in the community to consider the recognition of unsigned 16- and 32-bit integers, for two reasons: 1. With many instruments generating data in these data types, it is more efficient to avoid the necessity of data conversions, as was the argument for the introduction of the 8-bit unsigned integers. Twenty years ago, one had to scale anyway, so it did not matter. Now it does. Not too long ago, somebody in our community suggested that it was quite easy to make those instruments fit the standard. I think this is, well, arrogant, and putting the horse behind the cart: the FITS format is there to serve the flow of data from the instrument, not the other way around. 2. It has been recognized by most that one should preserve the original data from any instrument as much as possible. So, regardless of whether unsigned integers are easier, more natural, or more convenient, the introduction of unsigned integers as established data types provides the opportunity to store and transport that much more data in raw form, with fewer chances for mistakes. Context ------- XTE data will be coming down largely as 8-, 16-, and 32-bit unsigned integers. We have no use (or, at least, very little) for negative numbers and we intend to store those numbers in as raw a form as we can. Consequently, we have no intention of performing endless unnecessary scalings from unsigned to signed, and back. Proposed Implementation ----------------------- Actually, I am not sure how to implement this for the primary array, due to the somewhat kludged convention that is currently in use. One could either have assigned the negative numbers to the signed integers or, say, 17 and 33 to the unsigned versions, but the former clashes with the assignment of floating point numbers, while the latter prevents us from calculating the data length, based on this number. I would therefore suggest that we forget about the primary array and, as in the case of complex and double complex, concentrate our efforts on the binary tables. There are two possible solutions: 1. Append the letter "U" to the data type. A 16-bit unsigned integer would be represented by "IU", a 32-bit one by "JU". This has the advantage that it does not violate the current rules. However, it is somewhat distasteful since it looks like another ad hoc kludge. 2. Represent 16-bit unsigned integers by the letter "U", 32-bit ones by the letter "V". This choice of letters is reasonably self-explanatory since it follows the I-J convention. - Arnold Rots _---------------------Arnold H.

SAOimage comes up with a halftone display if the Default Visual for the server is StaticColor, DirectColor, TrueColor, GrayScale or StaticGray (most of the time). Use 'xdpyinfo' to check what the default visual is, you may be able to change this with some incantation to the PC-Xware (I can't say for sure since we don't have the hardware here I could experiment with). Is XV actually offering up 256 colors or just more than SAOimage? The IRAF Group at NOAO is currently supporting SAOimage although development of this task has been frozen for a while. If you still have questions feel free to write to iraf at noao.edu, we may not be able to dup- licate the problem but we're always happy to answer any questions as best we can. Hope this helps.

We have taken a different route with unsigned integers under Binary Tables. A new logical keyword was created, TSIGNn. If not present, the current "signedness" of the data types is used. If set to `T', it indicates that the field value is signed. If set to `F', it indicates that the field value is unsigned. Our FITS Table reader will only allow TSIGNn to appear for integer data types. This type of convention would also work for the PDU. It's completely backwards compatible (as is Arnold's). We chose a new keyword, rather than a new data type, to address PDUs (in case we ever need to do so in the future). We needed some- thing other than TZEROn and TSCALn, because our reader is very generic -- thus we cannot afford to perform any data conversions where loss of information is possible (we let the user decide how TZEROn and TSCALn are applied). +----. .' ----+--------------------------------+----------------------------+ | /| | | | | Tom Nicinski / MS 234 | nicinski at fnal.fnal.gov | | +-+-+\ | | Fermi National Accelerator Lab | _ | | . | | | \| | P.O.

The argument that one should keep the data in as raw a format as possible is one that I usually buy, but I would make an exception here since the transformation (just an offset, and no scaling) can be inverted exactly, to the very last bit included. It is also simple enough that even an industry contractor should be able to get the code right. I agree with Arnolds that "the FITS format is there to serve the flow of data from the instrument, not the other way around", but the flow one should have in mind is a flow to astrophysical interpretation, not to a tape vault. It may be worth putting a small extra load on the data writing group if it removes a bigger load on the readers (remember most astronomers still use fortran...). These restrictions apart, the proposal by Arnold Rots is a sound design for unsigned support if one decides unsigneds are needed. It fullfills the first rule for a FITS proposal: "Once FITS always FITS". The same is not true of the proposal by Tom Nicinski, which, contrary to its claims is NOT backward compatible. True, a FITS reader implementing this scheme will still read older FITS files, but the "once FITS always FITS" rule also demands that old READERS remain valid, not just old files. Extensions should be designed so that they can either be ignored for zero order use of the data (e.g. the world coordinate proposal), or so that they cause a gracefull crash (e.g. the floating point agreement). The TSIGNn convention is a sure recipe for producing junk whenever an innocent FITS reader ignores the convention and reads an unsigned column as signed.

Thanks. ... whilst I do not know of an elec version of the IAU Style Guide, Peter and others may be interested/reminded of the OGIP Memo "Specification of Physical Units within OGIP FITS files" (OGIP/93-001). This document follows the Style Guide very closely, and is available via anonymous ftp on legacy.gsfc.nasa.gov as caldb/docs/memos/ogip_93_001.tex (LaTeX source) caldb/docs/memos/ogip_93_001.ps (PS, 320974 bytes) The PS document is also accessible on the WWW via the URL http://heasarc.gsfc.nasa.gov/0/docs/heasarc/ofwg/ofwg_recomm.html Ian M George HEASARC
