Error while checking build/O2Physics/o2 for af1ffe9 at 2026-03-27 13:15: Full log here. |
1. Added configurable MCH alignment correction parameters in JSON format: The alignment corrections are applied to the MCH clusters on top of the realignment corrections, and before the track refitting 2. Added new method for vertex shift calibration: The new method is based on the linear correlation between the DCA(x/y) offset and the corresponding x/y track slope 3. fixed bug in the extrpolation of MFT tracks to the MCH clusters: The extrapolation was always done using the original MCH track momentum from the AO2D tracks, instead of taking the momentum of the refitted tracks when the realignment is applied. Now the refitted momentum is correctly used when available.
