7e24fa8c 1/****************************************************************************
2 * Very important, delicate and rather obscure macro. *
3 * ("a la" AliTPCComparison.C) *
4 * *
5 * Creates list of "trackable" tracks, *
6 * calculates efficiency, resolutions etc. *
7 * (To get the list of the "trackable" tracks one should *
8 * first run the AliTPCComparison.C macro) *
9 * *
10 * Origin: I.Belikov, CERN, Jouri.Belikov@cern.ch *
