Abstract
XCSAO is a software package for obtaining radial velocities of stars and
galaxies from optical spectra using the cross-correlation method. It
has been written to work within the IRAF environment, and is compatible
with other packages being developed at SAO for optical spectra. We
discuss the individual components of the package in terms of the
decisions required to set up the package for a new instrument/observing
program. Using artificial spectra we show the procedures necessary to
optimize the set up parameters, and demonstrate the robustness of the
package when applied to spectra from both stars and galaxies.
