[Sbs_gems] [EXTERNAL] BB cosmic results

[Sean Jeffas]

Hi All,

Sorry for the delay with these results, I had a few issues while rerunning
everything with the calorimeter based search turned off. The new results
are uploaded here https://logbooks.jlab.org/entry/3936858

We see now that the tracking is working fine from the cosmic data. Of
course, there is a misalignment from the whole magnet incident but things
look fine for all modules. In particular UV layer 0, which collided with
the magnet, looks normal.

Best,
Sean
