文摘

A robust technique with a sub-optimal weight function (M-estimate) was applied to investigate track fitting in cathode strip chambers (CSCs) and determine the CSC spatial resolution. The comparative analysis with the conventional least squares method was made on simulated data and experimental data from the Dubna CSC prototype. The results obtained definitely prove a necessity of using robust track fitting for a reliable estimation of muon chamber spatial resolution.
