Betsy, Jeff B., This afternoon we made a first pass at adjusting the M2 and M3 OSEMs to their mid-light positions. The adjustment went well. They are all within 200 counts of zero. A minor tweak was made to the T3 top OSEM. All these OSEMs will need final adjustments when the beam alignment is made. Betsy tightened the flat head screws on the 25 pin connectors. The loose one may be the source of grounds.
