Today we performed a laser intensity noise projection on Hrec by opening the PSTAB loop at 1249742972 and closing it at 1249743115. We took as a calm period for the projection the gps 1249742750, during 60 s.

Compared to the last projection (46453) the level of PD1 (out of loop error signal) is very different: it is now a factor ~200 below the sensitivity curve. This might be explained by a different working point of the ITF (to be checked), since the last projection was done during the single B1 PD operation.
