Physics shifter report (from C. Rogers)¶

• Following various studies and discussion at CM49, current working
  hypothesis is that the "50 MeV/c" momentum bump arises from changes to
  the track fitting. This represents about 10 % inefficiency in TKD. It is
  probably not related to hardware issues.
• Chris Hunt (who is the present physics shifter) did the study that
  demonstrated SSD M2 had incorrect polarity. I don't know if he has
  checked for the current settings that were in on Sunday.
• I did have a quick look at some data from Sunday morning and I didn't
  see any problems, beyond the known issues.
