5398f946 19/// \class AliMUONRecoCheck
78649106 20/// Utility class to check reconstruction
5398f946 21/// Reconstructed tracks are compared to reference tracks.
22/// The reference tracks are built from AliTrackReference for the
23/// hit in chamber (0..9) and from kinematics for the vertex parameters.

9bdda5f6 26// 13 Nov 2007:
27// Added a method to create a list of reconstructed AliMUONTrack objects from
28// ESD data. This is necessary since the track objects that are actually created
29// during offline reconstruction are no longer stored to disk.
30// - Artur Szostak <artursz@iafrica.com>
103e6575 31// 25 Jan 2008:
32// Use the new ESDInterface to create MUON objects from ESD data
