First step towards BigBite Optics for Pi0
Jure (the summer student) and I are looking at different runs
with Sieve-in and try to find sieve holes. We are particularly interested in
various focal-plane plots, because we believe, that first we first need to see
sieve pattern (of some sort) in Focal-plane, if we want to properly make
the optics. Without any visible separation in the focal plane bigbite optical
calibration will be very complicated.
Here are various focal plane plots. We noticed, that one paddle in E-plane
if firing far more often than the others. Is this physical or is this an
artefact? Is it possible that we have a light leak?
