6526a72c 10// Interface to AliMillePede2 alignment class for the ALICE ITS detector
11//
12// ITS specific alignment class which interface to AliMillepede.
13// For each track ProcessTrack calculates the local and global derivatives
14// at each hit and fill the corresponding local equations. Provide methods for
15// fixing or constraining detection elements for best results.
