Dr. William Pence Telephone: (301) 286-4599 HEASARC, Code 662 E-mail: William.D.Pence@nasa.gov NASA/Goddard Space Flight Center Greenbelt, MD 20771, USAThis User's Guide assumes that readers already have a general understanding of the definition and structure of FITS format files. Further information about FITS formats is available from the FITS Support Office at http://fits.gsfc.nasa.gov. In particular, the 'NOST FITS Standard' gives the authoritative definition of the FITS data format, and the `FITS User's Guide' provides additional historical background and practical advice on using FITS files.
The HEASARC also provides a very sophisticated FITS file analysis program called `Fv' which can be used to display and edit the contents of any FITS file as well as construct new FITS files from scratch. The display functions in Fv allow users to interactively adjust the brightness and contrast of images, pan, zoom, and blink images, and measure the positions and brightnesses of objects within images. FITS tables can be displayed like a spread sheet, and then modified using powerful calculator and sorting functions. Fv is freely available for most Unix platforms, Mac PCs, and Windows PCs. CFITSIO users may also be interested in the FTOOLS package of programs that can be used to manipulate and analyze FITS format files. Fv and FTOOLS are available from their respective Web sites at:
