update GRB_fremi_swift to do VCS obs for Swift triggers #8

Closed PaulHancock closed 4 years ago

PaulHancock commented 5 years ago

Since short GRBs are more likely to be associated with BNS mergers, or FRB like signals, and since our swift triggers are more likely to be short GRBS, we should be triggering in VCS mode in order to have the best chance at capturing this emission.

I am not sure if this is working as we have had a few Swift triggers recently with "trigger_dur = 1.024s" but these only activated the standard correlator rather than the VCS (as far as I can tell from the log files as "vcsmode" is set to "false"). See the following event from 18 Dec 2019 (plus attached log files, etc - unfortunately, the VOEvent wont attach): clear_SWIFT_944916.txt log_SWIFT_944916.txt schedule_SWIFT_944916.txt

The GRB Fermi+Swift handler triggered an MWA observation for a Fermi/Swift GRB at 2019-12-18 02:43:04.146 UTC.

Details are: Trigger ID: SWIFT_944916 RA: 20:04:18.624 hours Dec: -40:16:26.4 deg Error Rad: 0.050 deg Result: SUCCESS - observation inserted into MWA schedule

@gemmaanderson Github doesn't like .xml files for some reason. If you rename the voevent to have a .txt extension then you can upload it.

The VOEvent file has now been uploaded: voevent.txt

Cannot replicate ! Using the latest version of the software (19d740b) on my laptop with a python 2.7.14 environment, the voevent that you link sends a request that has vcsmod:True. This is the payload that is passed:

postdict={'freqres': 10, 'vcsmode': True, 'creator': 'VOEvent_Auto_Trigger_0.3', 'secure_key': '', 'pretend': True, 'calibrator': True, 'calexptime': 120, 'inttime': 0.5, 'nobs': 1, 'avoidsun': True, 'ra': 301.0776, 'freqspecs': '145,24', 'dec': -40.274, 'exptime': 30}
