Subject: T4 Comparison of calibration runs 
Attached is a comparison of two calibrations performed before the experiment (2 weeks and one day before) for Telescope 4 (the one having a degraded resolution in Ex on the offline).
One can see that:
  • The T4 resolution for strips X has been degraded between the two source runs.
  • The T4 resolution for strips Y remains ok and should be used for the analysis (slightly degraded only)
  • From the pedestal extrapolation, it also seems that there was a global drift for some channels.
