[Aavso-photometry] guide star catalog

[robin riordan]

I have been trying a photometry program for Linux called GCX. It
requires gsc field stars to perform frame photometry and the files must
be in binary (.gsc) I found the files at
ftp://cdsarc.u-strasbg.fr/cats/I/220/ but can't download them in a
batch. So, I thought if best to simply find a distributor of the GSC in
binary form on CDROM. I thought someone among this experienced group
might know of such a distributor.

Thanks,

Robin
