Evan, Sheila

This morning we had truoble with DRMI ASC.  THere are a few things that seem to have helped (in addition to intal alingment and some by hand alignment), and how the guardain is reliably getting to analog CARM. 

• The lock point of the SR3 cage servo was changed friday, changing it back to 931 (M3_WIT_P) and redoing SRC alignment seemed to help the SRC and MICH loops.
• Since the optimal yaw alingment of PRM seems to have changed quite a bit, I added an offset of 0.24 to POPA Yaw.  I also took out the lines in DOWN that were resetting this to 0 for each lock.
• Adjusting the current to the BS oplev laser reduced the glitching.
• The MICH ASC loops are now ramped on more slowly
• Evan increased the matrix element for REFL 135 Q to MICH by a factor of 2 (to 2.5) so that the MICH length ugf is around 10 Hz even when we are locked on 3F.
• This morning the mode cleaner was not relocking, and I was clearing the WFS history almost every lockloss.  This problem seems to have gone away for now.

Currently we are in a similiar situation as the last two nights, we can lock the interferometer but loose lock within a few minutes.  We have lost lock even while sitting on analog carm, we have been able to switch PRCL and MICH to POP sensors but suddenly lost lock about a minute latter.
