NEW icd-calibration

• ICD channels are now fitted as the calorimeter
  channels
• increment version number in DB version6
• good channels
• and bad channels
• ? 6 dead channels
• ?all channels in box 12 are bad
• ?2 types of bad channels
• nlc-problem / offset problem

ICD characteristics

box 12 2 populations
same behavior in the 3 other quadrants

ratio g

• slope is generally higher in ICD than in
  calorimeter
• small slopes correspond to box 12
