The purpose of the CLIC
ONOFF command is to make
single-dish spectra on all antennas simultaneously, using the current
spectral correlator configuration in autocorrelation mode. It can be
used to check frequencies, by observing a know line source, or to
provide the zero spacing flux in spectral line mapping. It is
recommended (but not compulsory) to calibrate before. The procedure is
started by the command
ONOFF Off1 Off2 [System] /TIME Time
where Off1 and Off2 are the offsets in arcseconds, System
is the type of offsets, and Time the integration time in seconds
(rounded to a multiple of 4 seconds).
