DEIMOS
mxy script

Name

mxy -- move telescope in instrument (detector) coordinates

Purpose

Offset the telescope a given number of arcsec in the
coordinate system of the DEIMOS detector. The offset is
relative to the current coordinaets by default; the optional
flag "-abs" causes the move to be made relative to the base
coordinates; i.e., an absolute move.

Usage

mxy [-D] [-n] [-abs] x y

Arguments

-D = debug mode
-n = no-action mode; only print move to be made
-abs = flag specifying that the move should be relative to
BASE position, rather than current position
x = offset in the direction parallel with CCD rows [arcsec]
y = offset in the direction parallel with CCD columns [arcsec]

Exit values

0 = normal completion
1 = wrong number of arguments

Example

1) Move telecope 10 arcsec along rows and -20 arcsec along columns:
mxy 10 -20
Note that since this is a *telescope* move, the target will
"move" in the OPPOSITE direction!

2) Move telecope 10 arcsec along rows and -20 arcsec along columns:
mxy 10 -20
Note that since this is a *telescope* move, the target will
"move" in the OPPOSITE direction!
