An astronomical camera control and data reduction program. GCX provides a complete set of data-reduction
functions for CCD photometry, with frame WCS
fitting, automatic target identification, aperture
photometry of target and standard stars,
single-frame ensemble photometry data reduction,
multi-frame color coefficient fitting, extinction
coefficient fitting, and all-sky photometry. It
also controls CCD cameras and telescopes, and
implements automatic observation scripting.
Cameras are controlled through a hardware-specific
server, to which gcx connects through a TCP
socket. The program can control telescopes which
use the LX200 protocol, and refine pointing by
matching images to the GSC catalog position of
stars. It generates FITS files with comprehensive
header information.
