simulator.observe - Function

2.4.1 Observe a given configuration

Description

Observe a given source with a given spectral window for the specified times, including start, stop, integration, and gap times.

If usehourangle=False (set with settimes), the start and stop times are referenced to referencetime.

If userhourangle=True, starttime/stoptime are interpreted as startha/stopha, the start and stop times are calculated such that the start time is later than the reference time, but less than one day later, and the hour angles refer to the first source observed.

setconfig or setknownconfig, setspwindow, setfeed, and setfield must be run before observe can be run.
