c25af45b 19/// \class AliMUONAlignment
20/// Alignment class for the ALICE DiMuon spectrometer
010eb601 21///
22/// MUON specific alignment class which interface to AliMillepede.
23/// For each track ProcessTrack calculates the local and global derivatives
96ebe67e 24/// at each cluster and fill the corresponding local equations. Provide methods
25/// for fixing or constraining detection elements for best results.
