SCAT in the Virtual Observatory
scat can be used as a filter in a CGI script as well as running as
a CGI program itself. In this case, it helps search and serve a catalog
of spectra and redshifts from the Smithsonian's Z-Machine reticon spectrograph
which was run on our 60-inch telescope on Mt. Hopkins in Arizona from 1978 through
1993. Output from scat is run through an awk script which adds the
links to CGI scripts using the ID number found by scat.
The links call a Fortran program to plot a spectrum, a C program
to list information about the spectrum, and IRAF SPP programs, through CL
shell scripts, to return FITS or ASCII pixel list files. The entire process
is managed by a Perl script.
