PSTAB noise projection on Hrec

Taking advantage of the Commissioning slot we performed a laser intensity noise projection on Hrec. The injection was made by opening the PSTAB during 60 s (gps 1247834598) and taking the gps 1247834418 as a calm period.

According to the projection the measured coupling is a factor 30 below the sensitivity curve.

To be noticed that compared to the last projection (45347) the two photodiodes (in loop and out of loop) have been swapped (46393), as well as the locking electronics (46278).
