calibration constant can find in: here
Note: SIS3801 have different constant with SIS3800
~3.17 3rm downstream scaler abnormal 3.18~4.2 LHRS upstream scaler noisy 4.2~4.9 RHRS SIS3801 scaler not working 4.9 changed RHRS scaler channel for bcm 4.19~ calibration constant changed Near 5.12 3rm sis3801 not working? 5.13~5.14 downstream broken
in constant area: blue available slope green available pedestal black not available
"in avail run area: black means not available same color in neighbour cell means same calibration constant"
