Run Readiness

Beni showed a live display of the TOF scalers. He is concerned about the FADC channel on the bottom (channel 31[?]) which is counting at a rate several hundred times the others. See the image below. Sascha Somov and Sergey Furletov have been told about this channel. Other quantities associated with this channel in the data look fine. Beni will keep an eye on it going forward.
