 SRM as set up in Atm4  26,000 count compared with ETMY oplev servo in operation 7,500 counts for 3 days

Next steps: measure beam size at qpd,

                  place qpd on translation stage for calibration,

                  change 1103P mount to single one

 SRM qpd is installed on translation stage and the shims removed from laser V mounts.

The ETMY oplev servo is on.

SRM oplev servo:  100 microrad/count is an estimate, not calibrated one.

 SRM qpd is back to its normal position. The mount base is still on delrin base. SRM and ITMY need centering.

Tomorrow I will set up the HeNe laser test at the SP table with Ontrack qpd

ETMY oplev servo on. SRM qpd with ND1 ------no component------- 1103P
