# my -- move telescope along columns in detector coordinate system
#
# Purpose:
#	Offset the telescope a given number of arcsec in the
#	coordinate system of the DEIMOS detector in the "y" direction
#	(i.e., parallel to detector columns).
#
# Usage:
#	my y
# 
# Arguments:
#	y = offset in the direction parallel with CCD columns [arcsec]
# 
# Exit values:
#	 0 = normal completion
#	 1 = wrong number of arguments
#
# Example:
#	1) Move telescope "down" by 10 arcsec as seen on DEIMOS:
#		my 10
#	Note that since this is a *telescope* move, the target will
#	"move" in the OPPOSITE direction!
