Noise in missing channels?
The first of these should be ring 13, straw 17; the other channels are not in use, slot 4 channels 48-71 are not connected to anything
Many bits missing from same channel (content of filled bins could be noise) ROC 25 slot 9 channel 14 missing bit 0 ROC 25 slot 9 channel 14 missing bit 1 ROC 25 slot 9 channel 14 missing bit 2 ROC 25 slot 9 channel 14 missing bit 7 ROC 25 slot 9 channel 14 missing bit 9 ROC 25 slot 9 channel 14 missing bit 10 ROC 26 slot 4 channel 49 missing bit 4 ROC 26 slot 4 channel 49 missing bits 7 to 11 ROC 26 slot 4 channel 61 missing bit 3 ROC 26 slot 4 channel 61 missing bit 4 ROC 26 slot 4 channel 61 missing bits 7 to 11 ROC 26 slot 4 channel 62 missing bit 3 ROC 26 slot 4 channel 62 missing bit 4 ROC 26 slot 4 channel 62 missing bits 7 to 11 ROC 26 slot 4 channel 63 missing bit 4 ROC 26 slot 4 channel 63 missing bits 7 to 11 ROC 26 slot 4 channel 65 missing bit 3 ROC 26 slot 4 channel 65 missing bit 4 ROC 26 slot 4 channel 65 missing bits 7 to 11
High end bits not populated
These are mostly strawless channels.
High end bits missing (not necessarily a problem, signals could have been small, could be strawless channels) ROC 25 slot 8 channel 35 missing bits 9 to 11 - connected to transition board but no straw ROC 25 slot 8 channel 37 missing bits 9 to 11 - connected to transition board but no straw ROC 25 slot 9 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 9 channel 59 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 10 channel 61 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 13 channel 13 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 13 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 14 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 14 channel 59 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 16 channel 11 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 16 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 25 slot 17 channel 59 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 4 channel 7 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 4 channel 11 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 4 channel 48 missing bits 7 to 11 - channels 48 to 71 are not in use ROC 26 slot 4 channel 60 missing bits 7 to 11 - channels 48 to 71 are not in use ROC 26 slot 5 channel 13 missing bits 9 to 11 - connected to transition board but no straw ROC 26 slot 6 channel 11 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 6 channel 61 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 7 channel 13 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 9 channel 33 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 9 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 13 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 13 channel 61 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 14 channel 61 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 15 channel 61 missing bits 8 to 11 - connected to transition board but no straw ROC 26 slot 16 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 3 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 3 channel 61 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 4 channel 11 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 4 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 5 channel 13 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 5 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 7 channel 17 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 7 channel 41 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 8 channel 61 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 9 channel 11 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 9 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 9 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 10 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 13 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 15 channel 59 missing bits 8 to 11 - connected to transition board but no straw ROC 27 slot 16 channel 11 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 5 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 6 channel 65 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 7 channel 13 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 9 channel 35 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 10 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 14 channel 31 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 14 channel 37 missing bits 8 to 11 - connected to transition board but no straw ROC 28 slot 16 channel 47 missing bits 8 to 11 ********** ring="15" straw="97" ********* ROC 28 slot 16 channel 59 missing bits 8 to 11 - connected to transition board but no straw
