LSC-Y_TR photodiode gain adjustment
I have turned up the preamp gain on the LSC-Y_TR photodiode (a PDA100A on ISCTEY) from 0 dB to 20 dB. The BS immediately before this PD is a BS1-1064-50-2037-45P.
The LSC-TR filter banks have been adjusted as follows:
LSC-Y_TR_A_LF: gain changed to 0.0185 from 0.185; offset changed from -30 to -40
LSC-X_TR_A_LF: offset changed from -180 to -171.

Somehow these values were overwritten with the old values around 2015-01-24 03:37:00 UTC. I've restored the new values.
