Subject: Oplevs centered, BHD DCPDs are now online 

[Paco, Yuta]

We have aligned the IFO (except for LO-AS and GRY), and centered all the oplevs.
We have also restored Gautam's in-air BHD DCPD setup and placed it to ITMY table.
BHD DC PD signals are now online at C1:XO4-MADC1_EPICS_CH4 and CH5. 

Oplevs:
 Aligned the IFO following the steps in elog 40m/16875.
 When we were woking on BHD DCPDs, we lost REFL beam on camera and both arms flashing. Alignment was restored mostly with TT2 pitch.
 We centered all the oplevs after the recovery (see attached).

BHD DCPDs:
 1. We removed a circuit box with M2 ISS photodetector readout board from AP table, in-air BHD photodiodes from optics graveyard. (see LIGO-E2000436 and elog 40m/15493 for wiring diagram)
 2. Taken out temporary two Thorlabs PDA100A used for aligning LO-AS during the vent from ITMY table, and placed the BHD setup in ITMY table (see attached and attached).
 3. DB9 cable (15ft+10ft) was connected from M2 ISS box to anti-aliasing chassis for ADC1 of C1X04 at 1Y2 rack (see attached).
 4. +/-18V power for M2 ISS box was supplied from 1Y1 rack.
 5. BHD DCPD signals are now available at C1:XO4-MADC1_EPICS_CH4 and CH5 (see attached).

Next:
 - Tweak alignment of green Y input to follow Yarm
 - Do LO-AS alignment
 - Centering of PDs everywhere with IFO aligned
 - Update RTS model for BHD
