This group is generated from the readout of 48 channels of CAMAC digital voltmeter located in the LGD hut. They contain information about:
adc_values_t
These DVM channels are read out at the beginning of every spill. The calibration of the probes are approximately as follows:
The map of channels to physical position is as follows:
