X arm transmission increased

Since the Faraday swap on monday, we have more green power. 

On the table we measured 50mW going towards the chamber, where previously we had measured 47mW (6% increase).  On QPD A we had a 10% increase in the sum, on QPD B a 30% increase in the sum.

Alexa and I measured 19uW arriving on ISCT1, compared to 12 uW measured in alog 9191 ( 60% increase from January)

We also noticed that the beam quality was better than it had been.  We measured some profiles, it is a guassian beam, they will be attached to this post later.

When the arm is locked we see a 35% increase in the transmitted power measured by the COMM BBPD, compared to last week.
