Name
rotang -- set/show physical DEIMOS rotator angle
Purpose
With no arguments, show the current DEIMOS rotator angle in the
DEIMOS coordinate system (which is approximately 90 deg off of
the rotator angle shown on FACSUM). With one numeric argument, set the
rotator to the specified physical rotator angle.
Usage
rotang [angle]
Arguments
angle = rotator angle [degrees]
Output
Current or new rotator angle [degrees]
Restrictions
- DEIMOS rotation must be enabled for moves to work
- DEIMOS must be under observer control, not DCS control
Exit values
0 = normal completion
1 = wrong number of arguments
Example
1) Show the current rotator angle
rotang
2) Set the rotator angle to 123.45 (DEIMOS physical system):
rotang 123.45
