Hello Lijuan and Bill,
I added a column to Hongfang's email below so the channels are numbered
1-72. The list from Hongfang more or less corresponds to a list I got from
Bill except for channel 65 and 66. What is wrong with those?
Also the list from Hongfang has most channels unreliable from 33 to
40. That would indicate something wrong with a TDC, not a module. (The
TDC is channels 33-40, the module is channels 31-36). Has anyone seen
anything wrong in channels 31 and 32? Has Bill seen "weird" behavior in
channels 37 and 40? Channel 38 was disconnected for most of the run
because the output from the re-discriminator on the platform was hot.
