CREAM 3 Data Quality Histograms

Data from 20071219: Launch LPT muon run. 3000 Events, except a few appear to have been lost in the communications link.
CVD threshold: 75 (standard). Prescale = 80.

NB: Today's state is the same TCD as the standard settings (noting that S3 thr0 is wrong in both). CVD HV both set at flight values of 1950.
Plots made with stump-0.6.3.

• -185337: We have accidentally been running with S3 thr 0 at 200 (PMT 16), as seen in these settings. 2840 events.
• -190006: Fixed S3 thr 0 back to 100: New standard settings.

Note: This is ground data, so we don't expect data in higher channels.
