Searching for bad sus aux monitor channels - Y arm

Ed, Keita, Jeff

So, a quick and nasty coherence check just to find possible dead monitor channels using a couple of frequencies reveals apparent bad channels:

ETMY M0: SD - voltmon, fastimon

           R0: F1 - noisemon

           L2: All Channels? - noisemon

ITMY  L1: UR fastimon

All suspensions in Y-Arm from TMS back to ITM were tested. Any not specified here measured good.

The fact that ETMY L1 shows apparent DC offsets, in the -4300 ct range in all noisemon channels, UL voltmon and LR fastimon, is not revealed by this measurement.
