Analytic calculation of coupling coefficients on the bullseye photodiode

Document #:

LIGO-T1700126-v1

Document type:

T - Technical notes

Abstract:

The purpose of this document is to calculate the response function for the bulls-eye photodiode and use that to arrive
at the calibration coefficients to be used in the filters used for the different aspects like pitch,yaw and beam size jitter.
