Detailed Description

Basic analyzer class which accesses 4D DTSegments and plots resolution comparing reconstructed and simulated quantities

Only true 4D segments are considered. Station 4 segments are not looked at. FIXME: Add flag to consider also segments with only phi view? Possible bias?

Residual/pull plots are filled for the reco segment with alpha closest to the simulated muon direction (defined from muon simhits in the chamber).

Efficiencies are defined as reconstructed 4D segments with alpha, beta, x, y, within 5 sigma relative to the sim muon, with sigmas specified in the config. Note that loss of even only one of the two views is considered as inefficiency!
