As in the previous releases of fv this version provides a graphical interface (written in Tcl/Tk) for editing FITS header keywords and for viewing or editing the data in FITS images and tables. 2D images and line plots of the values in table columns can be displayed. New features in this release include: - Compressed FITS files (gzip or Unix compress) can be directly read and viewed. - Astronomical images can be displayed with the axes labeled in units of R.A. and Dec. A grid of RA and Dec contour lines can also be overlaid on the image and the cursor position read-out shows the coordinates of the selected pixel. The user can interactively zoom in on any selected part of the image or line plot. - The intensity and contrast of the image can be interactively manipulated. - Tables can be sorted based on a primary column and up to 2 secondary columns. - A spreadsheet calculator can be used to create a new column or modify the values in an existing column. Users may enter any arbitrary arithmetic function which can include the values from other columns as arguments. - Full support for viewing and editing vector columns and variable length vector columns in binary tables. - Has a temporary 'cut and paste' buffer which can be used when editing rows or columns in a table. - Full support for null or undefined values in tables and images. - A central Window Manager provides more user control over the number of windows created and displayed by fv. - Image display is now supported on a wider variety of workstations including TrueColor displays. Fv currently runs on most Unix platforms. Versions for the Windows NT/95 and Mac operating systems will be available in the 1st quarter of 1998. Instructions for installing fv may be obtained from the Web site at: http://heasarc.gsfc.nasa.gov/ftools/fv.html Questions about fv should be sent to: ftoolshelp at athena.gsfc.nasa.gov.

It discusses where general FITS information, including some answers to frequently asked questions, can be found, and provides sources for detailed information on FITS software and documentation. ------- FITS Support Office The FITS Support Office maintains a library of FITS information accessible via http://fits.gsfc.nasa.gov/fits_home.html or ftp://nssdc.gsfc.nasa.gov/pub/fits/. The material available includes o "Definition of FITS", a codification of FITS for the NASA/Science Office of Standards and Technology (NOST), available in LaTeX, uncompressed PostScript, compressed PostScript and (often) ASCII text o "A User's Guide to FITS", published by the FITS Support Office, in LaTeX, uncompressed PostScript, and gzipped PostScript o Revisions to version 1.0 of the "Definition of FITS" covering the specification of units, which were incorporated into version 1.1 (text) o A current list of the extension type (structure) names registered with the International Astronomical Union FITS Working Group (IAUFWG) (text) o Rules for physical blocking on various media adopted by the IAUFWG (text) o The new format for DATExxxx keyword values endorsed by the IAUFWG, which provides for a four digit year, thus eliminating the year 2000 ambiguity of the old format, and for both date and time. (text) In the same directory as fits_home.html and accessible from it are four files that contain an update and expansion of the information that used to be in the FITS Basics and Information: o fits_intro.html: An overview of FITS o documents.html: A discussion of FITS documents o software.html: A discussion of software packages that support FITS, including FITS->image converters for various platforms, and a list of sample FITS files o info_sources.html: A discussion of on-line FITS resources Links are provided to many of the documents, software, and network locations listed. This FITS Support Office on-line material is continually revised to reflect current FITS developments. The file whats_new.html contains an outline of the most recent changes in the FITS Support Office Web pages and other developments in the world of FITS. There is also a hypertext version of the List of Registered Extensions. Links from the Web software page and a subdirectories of the main ftp directory contain o Software developed by the FITS Support Office. o Error test files: primary HDUs useful for testing the ability of software designed to read FITS files to cope with files that have errors or are non-standard. These files should be downloaded in binary form. Printed copies of the material in the FITS directory can be obtained from the Coordinated Request and User Support Office (CRUSO): (Postal) Coordinated Request and User Support Office Code 633 National Space Science Data Center NASA Goddard Space Flight Center Greenbelt MD 20771 USA (Electronic mail) request at nssdca.gsfc.nasa.gov (Telephone) +1-301-286-6695 8:00 A.

This machine supports a WAIS server named nrao-fits which has an index of all of the FITS-related text files in the archive; the file nrao-fits.src is available at ftp://fits.cv.nrao.edu/fits/wais-sources/nrao-fits.src. Some of the more noteworthy materials in this archive are o Text of any detailed proposals currently being discussed by the FITS committees o Drafts of other formally proposed additions to the FITS standard and of potential future proposals o A collection of documents on World Coordinate Systems, including the current draft proposal o Conventions specific to particular projects or disciplines o Software for various environments and Usenet postings about code o Sample data and special test files designed to measure the ability of a FITS reader to handle a wide variety of FITS files o Archives of traffic on FITS-related newsgroups and exploders A separate NRAO site, http://www.cv.nrao.edu/~bcotton/fitsview.html, provides information on the FITSview family of software packages for display of FITS images on Microsoft Windows 3.1 and Windows 95, Apple Macintosh, and Unix/X-Windows, with links to the software. It also links to a number of sources of astronomical FITS images. ------- HEASARC The NASA/Goddard High Energy Astrophysics Science Archive Research Center (HEASARC) Web server at http://heasarc.gsfc.nasa.gov/docs/heasarc/fits.html and the anonymous ftp access through ftp://heasarc.gsfc.nasa.gov/fits_info/ provide FITS material. HEASARC has developed the FITSIO package of software routines for easily reading and writing FITS files, with FORTRAN and C versions available, portable to a wide variety of machines. There are also the FTOOLS collection of software tools, the VERIFITS FITS conformance verifier, and the fv FITS file viewer and editor. HEASARC software is available directly through http://heasarc.gsfc.nasa.gov/docs/heasarc/tech_res_software.html or ftp://heasarc.gsfc.nasa.gov/fits_info/software/ . The HEASARC server also provides information from the HEASARC FITS Working Group, (HFWG) the internal legislative body on FITS-related matters within the Office of Guest Investigator Programs (OGIP) at NASA/GSFC, at http://heasarc.gsfc.nasa.gov/docs/heasarc/ofwg/ofwg_intro.html or at ftp://heasarc.gsfc.nasa.gov/fits_info/ in the directories ofwg_minutes and ofwg_recomm. The HFWG has developed a number of FITS conventions that are more specific than the requirements of the FITS standards. Proposed conventions are publicized to the FITS community as a whole, with the goal of collaborative development of a set of conventions that will be accepted throughout the community as well as within OGIP/HEASARC. ------- Direct questions about this posting to fits at nssdca.gsfc.nasa.gov The FITS Support Office is operated under the guidance of the NASA/GSFC Astrophysics Data Facility.
