I ran a noise budget injection into DC6 (centering loop for POP WFS), using a broadband excitation from 10-100 Hz. Based on the results in the DTT template (attached), there is not any measureable contribution to noise in DARM when injecting about 100x above ambient in the DC6 P control (bottom left plot, ref trace shows quiet time, live trace shows injection). We can include this channel in the ASC noise budget, but our code won't even generate a trace since the reference DARM and injection DARM shown here are exactly the same (top left plot, blue reference trace shows quiet time, red live trace shows injection time).

At a later time I will check DC6 Y.
