New RIN filter modules have been added to the ASC-OMC_A and ASC-OMC_B QPDs. The calculation divides the SUM input by the SUM output. The SUM filter modules by default load a 1 Hz 2nd-order Butterworth low pass.

New filters:

• H1:ASC-OMC_A_RIN
• H1:ASC-OMC_B_RIN

New frontend channels:

• H1:ASC-OMC_A_RIN_OUT (testpoint)
• H1:ASC-OMC_B_RIN_OUT (testpoint)
• H1:ASC-OMC_RIN_OUT_DQ (DAQ, sum of above 2 channels)
• H1:ASC-OMC_NSUM_OUT (testpoint, sum of the 2 NSUM channels)
