SCAT used over the World Wide Web
scat can call itself over the web. Code to turn http query input
into the same parameters which are set on the command line is built into
the main scat program. Code to assemble and send http queries to
remote programs, such as the ESO USNO-A2.0 and GSC servers and the STScI
GSC II server, as well as remote scat servers, is built into the
individual catalog access subroutines.
Since tab-separated Starbase tables, a native WCSTools catalog format, are an output
option on most catalog servers, they are parsed and sorted just like local
Starbase files.
