Detailed Description

Output of the two post-gain calibration steps.

Beam energy window. Gaussian-fits strip 0 (or strip 17) and reports mu ± 3*sigma in calibrated units, so downstream beam selection has one data-driven window rather than a hand-set threshold.

Strip centroid alignment. Decodes events with the per-channel gains already applied, finds each strip's beam-peak centroid from the eSum histogram, fits a robust degree-3 polynomial trend through the centroids with iterative outlier rejection, and derives a multiplicative per-strip factor = reference / centroid that pulls every strip onto that smooth trend.

Note: Both steps run after the anchor reduction and after the initial calibration tree is written — the alignment step needs that tree on disk so EnergyView can decode. The factors are then stored back into the calibration tree and applied by EnergyView after the per-channel gain.
