Purpose

Offset the telescope a given number of arcsec in the
coordinate system of the LRIS 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 LRIS

my 10
Note that since this is a *telescope* move, the target will
"move" in the OPPOSITE direction!
