keyword=HAND N2 Left iscriminator Ribbon Cable on wrongLooking at the data from since I unplugged and put back in the N2 left ribbon cable (Discriminator in bottom crate, slot 02), we're missing a histogram in the bottom channel of that ribbon cable. I think I put back on incorrectly. The ribbon cable is for N2-3L through N2-18L and (what's supposed to be) N2-18L is systematically missing. I believe that this means that the data that has been coming in since run 20446 is offset such that:
N2-3L's TDC is not in the data stream
NA.nd.p2.lt[2] is set to N2-4L (instead of N2-3L)
NA.nd.p2.lt[3] is set to N2-5L (instead of N2-4L)
NA.nd.p2.lt[4] is set to N2-6L (instead of N2-5L)
NA.nd.p2.lt[5] is set to N2-7L (instead of N2-6L)
NA.nd.p2.lt[6] is set to N2-8L (instead of N2-7L)
NA.nd.p2.lt[7] is set to N2-9L (instead of N2-8L)
NA.nd.p2.lt[8] is set to N2-10L (instead of N2-9L)
NA.nd.p2.lt[9] is set to N2-11L (instead of N2-10L)
NA.nd.p2.lt[10] is set to N2-12L (instead of N2-11L)
NA.nd.p2.lt[11] is set to N2-13L (instead of N2-12L)
NA.nd.p2.lt[12] is set to N2-14L (instead of N2-13L)
NA.nd.p2.lt[13] is set to N2-15L (instead of N2-14L)
NA.nd.p2.lt[14] is set to N2-16L (instead of N2-15L)
NA.nd.p2.lt[15] is set to N2-17L (instead of N2-16L)
NA.nd.p2.lt[16] is set to N2-18L (instead of N2-17L)
NA.nd.p2.lt[17] has no signal
