We noticed that the fast channels corresponding to H1:IMC-PWR_IN and H1:IMC-PWR_EOM were never hooked up. This required installing the PD interface box in the PSL enclosure, running the DAQ cable into the PSL and installing a tee in the photodetector readback. (These channels have previously been hooked up to the EtherCAT system, so they that they are available to the rotation stage.) The EOM channel is currently railed and needs an adjustment of the PD gain.

Another update:
I have put a filter in IMC-PWR_IN in order to calibrate the signal into watts. I used the slow readback (i.e. H1:PSL-PERISCOPE_A_DC_POWERMON) as a reference for the calibration such that IMC-PWR_IN matches to the slow one. So now the filter bank looks like this:
