ZTF collaboration meeting

• From Stockholm Suhail and Ana are going, nobody else from the SWG
• Jakob contacted Eric regarding a call-in timeslot for a talk
• Talk should update collab on current statistics and plans for cosmology paper

Observing strategy requests

• Need to assess losses due to twilight asteroid observations -> can be done with ztfquery
• Also need to see what fields would be good later in the year. How bad/how much worse is the weather then?
• Ariel suggested proposing deeper observations in high-cadence fields instead of more, would help lens search

ZTF cosmology paper

• Need to crunch over the next week to get some progress on this before the collab meeting
• Forced photometry: Rahul working on it, has code set up, may need better coordinates, i.e. not just based on first alert (AMPEL can provide that)
• Photometric sample: Jakob will generate this with AMPEL
• Suahil would like to redo H0 with new Hubble flow SNe from ZTF as comparison
• Yuhan's sample could be golden sample
• How should we determine distances? Simply fit alpha, beta? Probably good enough for our data

Agenda

• ZTF collaboration meeting
• Observing strategy requests
