No Fabry-Perot configuration is performed. If C1 is specified, a Fabry-Perot sequence is commanded. This LP permits a pattern of observations to be repeated rather than explicitly scheduling the pattern. This will be very useful for the transient observing mode. A table defines the offset times at which the various events in the camera exposure-readout cycle are to be performed, for each of the telescopes.
Calibration LPs The LPs that perform various calibration tasks are listed below.
In all cases the tables defining the camera parameters, the exposure times, the method of compressing the image, and, in the case of C1, the Fabry-Perot wavelengths, must be specified. A dark exposure is taken from a specified telescope. The shutter is not activated. The camera parameter table and exposure time are specified. The internal flow consists of camera setup, camera clearing, expose, image read out to the LEB, and compression and transfer to output buffer.
