Notes:

• Philip brought up that descrambling appears to not put the detector in the correct position. Dionisio has requested multi asic hardware for properly debugging this.
• Lorenzo presentation:
  • We should run at 2.6V, it improved the linearity (both v1 and v2 has been updated to supply 2.6V to the ASIC now);
