Calibration Measurement / DARM Loop Time Delay (Timing) Diagrams

Document #:

LIGO-G1601472-v4

Document type:

G - Presentations (eg Graphics)

Abstract:

After a mess of measurements and confusing diagrams, this is the attempt to culminate the results and clarify all possible ways we convey and/or measure the delays in the DARM loop.
