010eb601 21///
56218672 22/// MUON specific alignment class which interface to AliMillepede.
010eb601 23/// For each track ProcessTrack calculates the local and global derivatives
96ebe67e 24/// at each cluster and fill the corresponding local equations. Provide methods
56218672 25/// for fixing or constraining detection elements for best results.
