Beate:
- positrons rate uncertainties per day:
- benchmarking precision of 1e-3 but won’t be a disaster if not
- need to have >100 BXs…
- g+laser in phase1 to understand the bkg.
- look at Tony’s directory to see what’s existing

Sasha:
- need to check the impact of the casing of the calo?
- submit the jobs with this change while you check
- for next iterations: need the track_id from Tony to the HitTracks tree as well (like you did for the Tracks tree)
- note: there’s no backscattering from the dump since this volume is artificially killed (effectively like cutting this vertex).
- check acceptance of the calo in the current location for the high energy positrons (>12 GeV? Louis?)

Maryna:
- Landau fit?
- take what Sasha is processing now
- Sasha will process all the signal points, but then Maryna should take the spot-sizes: 5, 8, 10, 20, 50, 100
- zoom in on the ratio plot once we have the new signal processed (to give a statement on the error on the linearity) —> need to fit to a straight line.

Arka:
- will add the numbers for the b-only runs
- will add the g+laser sig and bkg runs
- will change to Sasha’s new files once we have those.
