sensor noise coupling to sensor output

Document #:

LIGO-T2500279-v2

Document type:

T - Technical notes

Abstract:

some math to describe what you expect when you look at the readouts of a servo loop which is dominated by sensor noise. This is relevant to understanding the tilt motion of the HAM-ISIs, among other things.

Version 2 includes new discussion about the supersensor
