Detailed Description

class to refit the ESD clusters/tracks

This class has been developped to simplify the re-reconstruction of the MUON tracks stored into ESD with different recoParams and/or after having re-calibrated the digits. It creates new MUON object from ESD objects given as input (through the ESDInterface) then:

re-clusterize the ESD clusters using the attached ESD pads (several new clusters can be reconstructed per ESD cluster)
re-fit the ESD tracks using the attached ESD clusters
reconstruct the ESD tracks from ESD pads (i.e. re-clusterized the attached clusters)

note:

connexion between an ESD cluster and corresponding MUON clusters from re-clustering can be made through the detection element ID
connexion between an ESD track and the corresponding refitted MUON track can be made through their unique ID

AliMUONTrack * AliMUONRefitter::RetrackFromDigits ( const AliMUONTrack & track )

private

refit the given track from the digits (i.e. re-clusterized the attached clusters): several new clusters may be reconstructed per initial ESD cluster: -> all the combinations of clusters are considered to build the new tracks -> return the best track (largest number of clusters or best chi2 in case of equality)
