[Primexd] [Revised Logentry] CCAL occupancy plots

[Justin Stevens]

Hi Sasha,

Can you make projections of your occupancies onto the X axis, near the beam hole?  It still looks like the occupancy is higher at X = +7 than X = -7, at least for Y values close to zero.  I think this can be correlated with Drew’s plots, but it’s not as obvious with these hit-level occupancies.
