The calibration of the green ALS PD in transmission of the arm cavity and located on ISCT1 have been remeasured. The responsitivity of the PD was changed to 0.22 A/W (from 0.755 A/W); a factor of 3.4 decrease. The beamsplitter ratio was measured to be 19% (from a theoretical 20%). The datasheet of the SM1PD1A indicated around 0.23 A/W at 532 nm.
