I think the workaround is to simulate multiple MSs then combine them with CASA virtualconcat/concat for further processing. We doing the same in the MeerKATHI pipeline when we have multiple files for a given observation, or using calibrator field from different observation.
But will try to implement this scenario in simms.
Indeed, that was my workaround too. Surprisingly it even works for VLBI MSs :)
This is now possible in one line! Here is an example:
simms -T kat-7 -date UTC,2014/05/26/12:12:12 -dt 10 -st 4 -sl 1 -sl 0.167 -sl 0.1 -f0 1.4GHz -nc 10 -dir J2000,0deg,-30deg -dir J2000,0deg,-40deg
This will observer the first field (J2000,0deg,-30deg) for 1 hour, then the second field (J2000,0deg,-40deg) for 0.167 hours (10 minutes) and repeat until 4 hours is reached.
Stale. Closing
Before implementing this manually, I thought I'd ask those involved with simms if they have thought about simulating phase-target loops. I know of the scan lag option, but this won't really work (or offer sufficient flexibility) for the application of generating a realistic observing schedule, where we have a nodding between phasecal and target with some duty cycle and the associated slew-time gaps.
