|Usage:||focusrun [<camera_name>] <num_exposures> <exp_time>
|Category:||Observing System Script|
|Description:||This commands builds on the services provided by UltraDAS
to provide a means of performing a sequence of scratch observations at
varying telescope focus settings. The sequence of scratch observations
are stored in the current observation directory as files s1.fit, s2.fit
|Arguments:||camera_name specifies the formal name of
the camera to be used for the focusrun sequence. This parameter is optional
if only one camera is currently available.
num_exposures specifies the number of exposures to be performed during the focusrun procedure.
exp_time is the integration time specified in seconds to the nearest millisecond.
start_position specifies the start focus setting of the telescope.
focus_increment specifies the increment
of the telescope focus setting to be made after each exposure.
|Examples:||focusrun ingrid 10 6 79.0 0.1 - perform 10 scratch run observations starting at a telescope focus of 79.0, and incrementing the telescope focus by 0.1 for each subsequent scratch run observation. The files s1.fit to s10.fit are created in the current observation directory.|
