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