Updating Pcal combined displacement correction factors and evaluating Pcal systematic errors during the O4b observing run

Document #:

LIGO-T2400108-v3

Document type:

T - Technical notes

Abstract:

We detail the calculation of updated Pcal combined displacement correction factors
when end station responsivity and optical efficiency values are updated. We describe a
scheme for evaluating systematic errors in the Pcal fiducial displacement calibrations
for the O4b observing run.
