iraf-2.11 Currently available on Solaris 2.6 and linux machines only. Check out the help pages at NOAO for version 2.10 for starters. If you think it would be useful to have a mirror copy of this documentation or a subset of it at CFHT locally, please pass this on to Kanoa. saoimage-1.19 (or go to the Web page) The ever-popular FITS viewer. (Note: Man page still says 1.18.) ds9 Next generation FITS viewer supports mosaics and monitors with more than 256 colors. skycat-2.0 A new FITS viewer with cool ways to connect to catalogs over the Web. We are currently looking into integrating skycat into observing sessions. There are now three versions of skycat available: skycat-1.0, skycat-1.1, and skycat-2.0. None of them handle colormap adjustments correctly. "skycat" by itself currently just brings up our latest version from March 1999 (2.3.2). If you experience slow startup (because it tries to contact ESO's Web server) you might try setting the environment variable SKYCAT_CONFIG to "http://www.cfht.hawaii.edu/skycat/skycat.cfg" so that it contacts our Web server instead. PGPlot-5.1 Perl-based plotting package. The link above gives a list of functions included in the library, which is installed in /apps/gnu/lib/pgplot/. cfitsio-1.30 According to The FITSIO Home Page, FITSIO is a subroutine interface for reading and writing data files in FITS (Flexible Image Transport System) data format. Separate FITSIO libraries are available for use with programs written in Fortran-77 or ANSI-C. The C-version ONLY of this library is now installed with links in /usr/local/lib/. The include files are in /usr/local/include/cfitsio/, so preferably your programs should be compiled with -I. and use #include "cfitsio/fitsio.h".
