Detailed Description

The SegmentFittingAlg fits straight lines to the Mdt/Rpc/Tgc hits associated with the SegmentSeedPatterns.

The pattern parameters in the bending direction are refined by constructing the tangent to two Mdt measurements and then by associating other measurements to the seed. If the procedure succeeds, the hits are passed through the straight line procedure. At the end of the fit, ambiguities amongst the segment candidates are removed based on the degrees of freedom and the chi2 fit quality

Fit the hits from the pattern seed to segment candidates.

Tangent lines to a pair of drift circles are constructed. The remaining hits are associated based on their chi2 compability. Good seeds are then fitted to segments including an outlier rejection and hole recovery procedure

Parameters

ctx	Event context to access the conditions data needed for calibration
gctx	Geometry context to access the transforms of the particular reference surfaces.
seed	The segment seed from which the parameters in non-bending direction & the associated hits are taken

Draw the pattern with all possible seeds
