List of known "anomalies" (to be checked):

  • Bad strips > 60%, n-side of -405 and +405
  • Bad strips 100% n-side of +110, +111, +112, +211, +311, +411
  • Bad strips 100% s-side of -609
  • Calibration difference > 10 ADC -609 and +405

After new second step calibration:

  • High occupancy ladders: n-side of -810, -510, -611, (january) +810, +109
