Key findings
Achieves center-of-mass offset calibration accuracy better than 1 um.
Scale factor precision better than 0.05%.
Real-time sliding-window implementation shows convergence within minutes.
Limitations & open questions
MCMC computation cost may limit update frequency.
Assumes Gaussian noise structure, may need extension for non-Gaussian effects.
