(File updated 9 June 1993 11:15 am EST ; Announcement of Proposed Standard replacing Draft Standard.) Note: all information files are now in the form AAREADME.DOC. The old files have been eliminated. This main directory contains copies of version 1.0 of the NASA/OSSA Office of Standards and Technology (NOST) Proposed Standard NOST Definition of the Flexible Image Transport System (FITS). This Proposed Standard has been approved by consensus of the NOST Technical Panel following review of the comments received on version 0.3 of the Draft Standard. The most significant change is the clarification that only the specifically defined commentary keywords, COMMENT, HISTORY, and columns 1-8 blank, may have '= ' in columns 9-10 without a following value. Otherwise, if '= ' is present in columns 9-10, the keyword must have a value. The informational appendix on IEEE special values, which is not part of the standard, has been expanded. This Proposed Standard is being submitted to the Accreditation Panel for approval as a NOST Standard and to the IAU FITS Working Group for endorsement as the Standard for FITS. Although the formal comment period has ended, general comments or questions can be sent to the address at the end of this file. The new version is being made generally available before final action by the Accreditation Panel to allow those who may have been using the Draft Standard as a reference on FITS, in spite of its provisional status, to replace it with the Proposed Standard. Use of superseded versions has caused problems in the past. This Proposed NOST Standard should not be considered to supersede the existing FITS documentation as the international standard for FITS. This directory also contains a list of the extension type names that have been registered with the IAU FITS Working Group. The file containing the list includes a brief summary of the extension type corresponding to each name, the developer, and the status of the extension. Also described is the procedure for registration of extension type names. This file will be updated from time to time as new extension type names are proposed and extensions corresponding to reserved names progress through the process required for IAU FITS Working Group approval as a standard extension. As a result, it should be used rather than the appendix in the Standard covering reserved extension type names, because the XTENSION.LIS file will be more up to date. The text of one proposal for a new extension type, the IMAGE proposal of Ponz, Thompson, and Munoz appears in the directory. Readers should be aware that this extension type is at present only in the *proposal* stage and is subject to revision as a result of community review, until a final form has been approved by the IAU FITS Working Group. In the meantime, anyone using the specific type name IMAGE must make sure that their files remain in conformance with the current rules. Keep up to date on developments through the USEnet newsgroup sci.astro.fits or the fitsbits mailing list (to subscribe, send mail to fitsbits-request@nrao.edu). There are two subdirectories The SOFTWARE subdirectory contains software and information about publicly available software. It is described further in the AAAREADME.DOC file it contains. The ERRTEST subdirectory contains a number of sample FITS primary HDUs with a variety of deliberately inserted header errors, for use in testing FITS readers. Further information is in the AAAREADME.DOC file of the ERRTEST subdirectory. The FITS directory contains the following eight files: AAAREADME.DOC;1 Information on the Proposed Standard FITS_STANDARD.PS;1 PostScript version of the processed LaTeX file FITS_STANDARD.TEX;1 LaTeX source file for FITS Proposed Standard FITS_STANDARD.TXT;1 Flat text version of the FITS Proposed Standard FITS_STANDARD.IND;1 LaTeX index file.
