Calibration Status since vent recovery
We have a preliminary report for the calibration status of LHO after the vent recovery, based on the measurement taken in LHO:79691. The report can be found here.

Taking a look at the PCALY to (GDS-CALIB_STRAIN_CLEAN) DARM broadband injection, there is an elevated amount of error between 30 and 60Hz. It would be worth considering to update the calibration at the next available opportunity, but it isn't pushing us beyond 10% mag/10deg phase yet. This is also corroborated by the monitoring page here.

N.B. I used pcal to GDS instead of to DELTAL_EXTERNAL because the GDS channel is already calibrated to meters for us.
