NF1611 photodiode taken from ISCT6 and put iinto ISCT1 in front of ASC WFS Reflair A.  There is 6mW coming from REFL-BS3, then we placed the 1611 behind a 90% 45-P beamsplitter.  There was .4mW of light incident on the 1611 when looking at a prompt reflection from the PRM.   The PSL was running at 2.3W. The aux laser was running at 500mW, 0.5mW reached the pd.  I unplugged the power to the BBPD Refl photodiode (Reflair B) to power the 1611. 

The alignment of Aux laser and carrier onto IOT2R was adjusted to maximise the power of both beams onto the 1611PD on this beam.  I tried to lock the aux laser to the carrier frequency plus a fixed offset using a servo controller, same settings as previously, but have not yet succeeded.  To be continued tomorrow.
