Detailed Description

FairTrackParam.h

Author: V.Friese v.fri.nosp@m.ese@.nosp@m.gsi.d.nosp@m.e

Parameters (x, y, tx, ty, q/p) of a track resulting from the track fit. The z coordinate is not a parameter. The 5x5 covariance matrix can be set and accessed by either an array of size 15, the TMatrixFSym class or elementwise. Note that TMatrixFSym should not be used when performance is an issue. The internal representation of the covariance matrix elements is an array of double.
