Here are the R-arm VDC wiremaps cut on time and event type 4 (L/R scintialltor coincidence). No obvious malfunctions, aside from one dead wire in u1, a known problem.
As with the L-arm, the spectra show too much structure overall. I suspect that the high-gain amplifier cards are too noisy and/or sensitive to crosstalk.
