FITSview family update

[Bill Cotton]

            Update of FITSview Family (Windows, XWindows, Macintosh)
                             April 14, 1998

   Updates of the FITSview family of FITS image viewers are now
available for FITS format astronomical images.  These viewers feature
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 for WCS,
DSS and IRAF CD-matrix positions.  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.  In addition, gzip compressed files may be read directly.
Extensive online documentation is included.

This release features 1) more intelligent guesses of the
range of pixel values to display for high dynamic range images, 
2) a histogram equalization option and 3) support for IRAF
CD-matrix positions.
