No lock tonight

Attempted to bring the interferometer back to 40W in an attempt to leave it at 40W over night.

- Slightly tweaked the yaw offsets of the QPDs to improve the PR gain, but ran out of patiance at a recycling gain of 28 - I think there is more to be had with better alignment..

 (The offsets I used were in the control filter modules: H1:ASC-DSOFT_Y_OFFSET=0.08, H1:ASC-CSOFT_Y_OFFSET=0.04)

- Then the OMC DCPDs started saturating - for now I just turned off the PD whitening.

- Added the input matrix from alog  to Guardian - but Guardian still does not turn the SRC1 loop on when it gets there.:

for SRC1_P:
AS_A_RF36_I : -0.5
AS_B_RF36_I : +1.0

for SRC1_Y:
AS_A_RF36_I : -1.5
AS_B_RF36_I : +0.34

However, the soft loops ran away several times during powerup - not sure what changed.
