pupil hnum commandiSet pupil position
This command sets the pupil position. If no pupil number is given, a list of available pupils are g ven and the current pupil position is shown. If the pupil number is different from the current, the pupil slide is moved to the new position. Note that the positions are separated by 7500 steps of the motor, so it takes many minutes to move to a new position. T e pupil can be moved to the reference position by typing pu home.
The command pu switch will report on the position of the pupil/filter wheel 2 switch. The same motor controller is used for these motors, and only one can be in operation at any time, selected by the switch on the utility (black) box on the QUIRC dewar. This command tells whether it is in the PUPIL or FILTER position.
For fine adjustment of the pupil position, the commands pu FO and pu BA will move the pupil 10 or

set hparami[n]Set parameter
Certain program parameters can be set or unset with this command. To set a param- eter, for example “save", one issues the command set save. To unset, the command set nosave is used. Alternatively, one can type set save 1 and set save 0 to turn it on or off. Below are the available parameters:
clobber – If on, existing files will be automatically overwritten. If off, the program will ask for confirmation from the user before overwriting files.
chop – Turns chopping on or off. Also can be set via the auto command.
beep – Causes the program to beep after each detector readout, and other operations. Can be annoying.
vfout – Directs qcdcom to send commands to vf to display the most recent image.
save – Turns auto save on or off. Also can be set via the auto command.
longshut – Sets the long shutter mode. In this mode, the shutter is opened before the initial reset of the observation is done, and keeps it open until after the final read is completed. Because of the array read time, the minimum integration time is about 11 seconds. This mode can be used if one wants to avoid the background from the warm shutter when taking exposures of faint fields. Note that if any bright objects are in the field the detector will likely saturate on those sources.
