# gxy -- move the telescope in GUIDER coordinates
#
# Purpose:
#	Offset the telescope by the given number of arcseconds in the
#	guider coordinate system, which is rotated 180 degrees relative
#	to the DEIMOS coordinate system.
#
# Usage:
#	gxy x y
# 
# Arguments:
#	x = offset in the direction parallel with guider rows [arcsec]
#	y = offset in the direction parallel with guider columns [arcsec]
# 
# Exit values:
#	 0 = normal completion
#	 1 = wrong number of arguments
#
# Example:
