Participants (13):

• Mickael R, Mat S, Joel J, Melissa A, Jacco T, Young-Lo K, Suhail D, Eric N, Bastien C, Ariel G, Philippe R, Dominique F, Estelle R
• Apologies: Remy J, Jakob N, Kate M

Transients of the Week:

• ZTF21acljgsm: is an old SN that's suddenly started being detected in g-band.
• ZTF21acjvjyk, ZTF21aclhsxb, ZTF21aclzodp, : caught early - will be prioritised for a spectrum at peak
• ZTF21acjtxgr: 91T on the rise
• ZTF21acjgmiy, ZTF21acjgafq, ZTF21acjbqrn: highly extincted SN caught early
• ZTF21acjxjpu: typed by 'the zooniverse' as a Ia-CSM: it isn't! This is a new 'feature' that should be discussed :).
  • Let's use the fritz-users space for this!

Simulations:

• Who's working on simulations?!
  • Melissa (working on anistropies); Suhail (working on populations); Mark M (working on rates)
• Key questions:
  • are we all doing different things? Answer 'sort-of': let's talk about it!
  • are we using the same inputs? Answer 'maybe': let's ensure we are all starting from the same point
  • Let's have a zoom meeting by the end of month to talk about simulations and output papers :).

DR2 Updates:

• Misc: Jakob is setting up a meeting between the 'light-curve' teams
• Mickael: the Paris group are setting up the SMP pipeline: if it works then maybe the DR2 release will switch to that
  • Question: can we use that instead of FP everywhere?
  • Answer: probably not: FP is easy and so great for early time information.
  • Discussion: why are the FP light-curves often so different from the alerts?
    • Answer: ?!

Closing remarks:

• Fill in the spreadsheet to volunteer.... Georgios last week was a great example of it being a positive experience :).
