[Sbs_gems] [EXTERNAL] BB cosmic results

Hi Andrew,

Ok I had no idea about the calorimeter based search. I will re run it.

I just added the pedestal plots to the HALOG as well. It looks like the
pedestal is pretty good except for J0, which has drifted again. I agree
some of the ADC distributions look a little bumpy, but they are often like
that when looking at cosmic data, before cleaning them up with good
tracking.

Best,
Sean
