    keyword=Pion Rejector Not Aligned

    I found that the HV map for the pion rejector does not reflect the
    signal channel map or at least what I expect. Without this
    information, I cannot do the HV alignment. I have the data that I need. However the cable map needs to be fixed. As far as I can tell,
    the pion rejector channels are all over the place.

    For example, when I turn pion rejector layer 1 channel 28 off, PR
    layer 2 channel 11 had no signal in the ADC. When we turned off
    channel 11 from layer 2, channel 16 in layer 2 had no signal in the ADC. Hence it seems that not only are channels swapped within the
    pion rejector layers but also among both of them.
