HWS plates replaced on ETMX and ETMY HWS.  We shifted the beam path on the ETMX HWS path to get the dimmer refection from a wedge, to drop the power on the HWS. (This is now the lowest power we can get with the current optics.)  The power level onto ETMX HWS looks good, the CCD is mostly unsaturated with the plate on.  I have changed the exposure time to 13000microseconds, down 20% from the previous 16000microseconds setting.  There are about 30 saturated pixels at this setting.  ETMY HWS image is too saturated.

ITMY HWS path is aligned to the green beam again. (This alignment changes every time the SR2 and SR3 alignments change).  However the ITMY SLED is dead.  We need to swap out this SLED and adjust the maximum power levels on the ITMX and ITMY sleds.
