The rdark command is used to take a dark frame. The length of the dark (in seconds) is specified with the -t option. The dark will be placed in the path specified in camerad.conf, usually /rotse/data/3a1/. The name follows the standard naming convention described in Chapter 3, with ``drk'' as the three letter acronym, and the field replaced by the exposure time multiplied by 10. For example, the second 60 second dark image taken on March 15th, 2002 will be given the name 020312_drk0600_3a002.fit.
The rexpose command is used to take an exposure. The length of the exposure (in seconds) is specified with the -t option. The name can be up to 8 characters (this needs updating!) and replaces the three letter acronym and number in the standard naming convention. The exposure will be placed in the path specified in camerad.conf, usually /rotse/data/3a1/. The exposure counter at the end of the name is automatically updated by the daq system, so up to 999 images of the same name can be taken on the same day.
The rabort command is used to abort an exposure (image or dark) in progress. If the camera is reading out the abort will take place after the readout is finished. If no exposure is taking place this command has no effect.
The rsettemp command is used to set the CCD temperature. This overrides the default set in camerad.conf (see Section 3.5).
