Comment to Shot noise changes with higher laser power (40134)

It is likely that the discrepancy of the power "stored" in the arm cavities or transmitted through the end mirror and the increase of input power is related to a different mode matching originating from a different thermal lens in the SIB1 Faraday isolator and PR or cavity mirrors. When we will recommission the ITF we will have to readjust the mode matching.
