|Observing System Command
|This command builds on the services provided by UltraDAS
to provide a graphical user interface (GUI) for performing a quick focus
observation. The quick focus observation takes a sequence of exposures
at increasing telescope focus, offsetting the telescope north at each exposure.
The first spacial offset will be twice the subsequent offsets. A single
observation file in the normal run number sequence is produced, and is
stored in the current observation directory.
|camera_name specifies the formal name of
the camera to be used for the quickfocusrun observation. This parameter
is optional if only one camera is currently available.
number of steps specifies the number of spatial steps to be performed during the quickfocusrun observation.
size of spatial steps is the size of the telescope offsets (in arcseconds) between exposures.
size of focus step specifies the increase in telescope focus (in mm) between exposures.
starting focus specifies the telescope focus at the start of the exposure sequence.
exposure length specifies the exposure time for each step of the focus sequence.

quickfocusrun can be used in preference to the normal
focusrun command to provide a faster method of focussing for imaging cameras.
