The ftpd server was built from the WU-FTPD code. This facility concerns over 1,000 tables for which we don't require to build and maintain FITS versions. We hope that the FITS generated is standard --- however we have conventions for UNIT which differ from the proposed OGIP ones, and we do allow column names with non-alphanumeric characters.

The only likely requirements on units are those in the current draft put out by the NOST Technical Panel. However, it will be best for all concerned if those producing data in a particular discipline, such as high energy astrophysics, can agree on a set of conventions to be used in that area. OGIP is making an important contribution to this end by developing its detailed set of conventions. But these conventions should not be treated as a set only for OGIP, with other conventions to be developed elsewhere. The idea is for the OGIP drafts to serve as the basis for development of universal conventions to be used in high energy astrophysics and perhaps elsewhere. In this context, those who see problems with the OGIP conventions in a particular area or whose local preference in a particular area is different should bring the specific issues here for public discussion, to allow movement towards a consensus convention.

Barry Schlesinger suggested several minor changes, and these were accepted by the authors.

So far our test corpus has a good number of regular 24-bit true-color and 8-bit (or less) color-mapped images, but we need some with 16 bits per color. (We have considered creating 16bps images out of 8bps ones, but they would be extremely small and not necessarily representative of real 16bps images). Some 12-bit medical images would be nice, too. If you either (1) have some, (2) have some way to generate them, or (3) have a pointer to some somewhere on the net, please send me e-mail with details (assuming you're willing to donate a few for testing purposes only). We can probably deal with most reasonable formats. (PGM/PPM would have been pref- erable if they supported 16bps in binary mode, but they don't. Oh well.) Btw, for those in s.a.f and s.m.* who don't know what PNG is: it stands for "Portable Network Graphics" (or, unofficially, "PNG's Not GIF") and will be a lossless replacement for the GIF format with support for up to 16-bit color depth. The compression method is deflation, the same as in Zip/PKZIP and gzip. (Completely mindless tests of color-mapped images with LZW [GIF] vs. deflation shows 10% improvement in compression even without any special fil- ters. I don't have any numbers to compare with lossless JPEG.) Note follow-ups.

Thank you. From Ron Baalke at JPL: ================== IMDISP 7.7 October 8, 1991 ================== Version 7.7 of the IMDISP program has now been released. 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 7.7 is available via anonymous ftp at ames.arc.nasa.gov [128.102.18.3] in a file called imdisp77.zip in the pub/SPACE/SOFTWARE subdirectory. It will also be available through simtel [192.88.110.20] at PD1:IMDISP77.ZIP. IMDISP77.ZIP consists of the following files: IMDISP.EXE - IMDISP program version 7.7 IMDISP.DOC - User's Guide for IMDISP 7.7 PALETTES.ZIP - Color palette collection 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. Any feedback to the IMDISP program is highly appreciates. Any problems encountered and suggestions for improvement can be sent to the IMDISP programmers listed below.

But you can just bypass the header by calculating the image dimensions (eg, header = filesize - (xdim * ydim * 2)). Byte order is little endian. CTs are 512x512, MRIs are 256x256.

The title and URL are "Specifications concerning designations for astronomical radiation sources outside the solar system" http://cdsweb.u-strasbg.fr/iau-spec.html I have studied this document, and have concluded that the FITS community should consider it for adoption as a recommended practice for OBJECT values, in much the same spirit as our endorsement of the IAU Style Manual recommendation of SI units. All members of the FITS community who are interested in the strings that go into the value fields of OBJECT keywords should read this document. Problems of object identifications in data archives (and in the published literature) will be reduced if these recommended practices are followed in observatories. Questions: 1) Have any observatories recommended to their observers that the IAU rules be followed in entering source name strings (which become OBJECT values)? Should all observatories do this? 2) Have any archives utilized or enforced these rules in any way? Should archive systems do this? 3) Has anyone coded a parser to check conformance of strings to these rules? Would such a tool be useful? -- Donald C.

Thank you. This is a description, and source of the best such viewed available: FITSview (0.4.0) for MS Windows 20 January 1995 This is to announce the availability of an updated version of the beta release of FITSview for MS Windows. This release includes the new features of optionally loading an image upside down and logging selected or fitted pixel positions in a text file. Many small bugs were fixed and the program was translated from c++ to c to improve its reliability. 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/fitsview/fitsv040.txt ftp://fits.cv.nrao.edu/fits/os-support/ms-windows/fitsview/fitsv040.zip Installation is described in file fitsv040.txt.

IRAF V2.11 will include a FITS image kernel so converting the FITS files won't strictly be necessary then. V2.11 will also include two new tasks for image conversion (these are available now in an external package called IMCNV, see ftp://iraf.noao.edu/iraf/extern/imcnv.tar.Z) that will allow you to convert IRAF images (or FITS in this case) to some other format (EPS, GIF, rasterfiles, others) directly. Using the EXPORT task you can create e.g. a 24-bit rasterfile that combines your three input images, you can also use the same colormap generation algorithm as in the COLOR package to create an 8-bit colormapped image. Color EPS is supported and the task provides a general arithmetic expression evaluator so input images may be combined as mosaics and intensity values can be mapped to 8-bit in a number of ways. For formats that aren't currently supported (e.g. JPEG and TIFF) you can write out something like GIF and convert using some other utility. The IMPORT task allows you to convert other formats into IRAF images. This package is available on a test-release basis now, if you find any bugs or have any questions or suggestions let me know.

If I remember correctly the program reads in formats like FITS, PDL, GIF and one or two others. The NASA folks on here could elaborate a bit further. In either case with the version I have a few years back you were able to combine multiple buffers. I believe this is what you looking to accomplish. Well good luck!

Date: 28 Feb 1995 06:47:29 GMT There is a very well written DOS based NASA image data viewer. It is indeed called IMDISP and is available from Compuserve in one of it's Space related forums. I don't recall exactly which one, but I downloaded it recently. It shouldn't be hard to find. It allows for some very good buffer-based filters and processors, also exports to GIF! AGL -- :A:G:L:
