Sorry. I had also meant to cc my email below to the MWL-Board.

Subject: Sharing HESS AGN schedule with CSIRO
 
Dear AP team,
 
I've been in discussions with Phil Edwards (Head of CSIRO Science Operations for ATNF, operating the ATCA radio facility) regarding AGN targets for their regular monitoring campaigns with the ATCA facility.

Phil has expressed a keen interest in improving or optimising the monitoring cadence for the various TeV AGN that HESS is observing. The results of this feed into the publicly available ATCA Calibrator Database

 https://www.narrabri.atnf.csiro.au/calibrators/calibrator_database.html

and also to the TANAMI project, carrying out VLBI for hi-res studies of active AGN in the south.

As you may know, these projects are beginning to shift their focus to include TeV-detected AGN in recent times.

Would HESS be willing to share with Phil our AGN observing schedule, planned and achieved? Precise observation times are not needed.

A rough schedule on a monthly (period) or even weekly (if possible) would be sufficient. The information would be kept confidential and only appear in public in the calibrator database in the form of higher-cadence sampling for those particular AGN, in they are not already.

It's expected that major TeV flares from HESS would be communicated via ATels, but if needed, we could also consider sharing such information privately to increase the cadence for their ATCA monitoring. I'd be happy to draft a basic information sharing agreement if it's thought that is needed for these special cases.

all the best

Gavin..
