7f6ddf58 | 1 | /**************************************************************************** |
2 | * Very important, delicate and rather obscure macro. * | |
3 | * * | |
4 | * Creates list of "trackable" tracks, * | |
7f6ddf58 | 5 | * calculates efficiency, resolutions etc. * |
bf018fe4 | 6 | * There is a possibility to run this macro over several events. * |
7f6ddf58 | 7 | * * |
024a7fe9 | 8 | * Origin: I.Belikov, CERN, Jouri.Belikov@cern.ch * |
7f6ddf58 | 9 | * with several nice improvements by: M.Ivanov, GSI, m.ivanov@gsi.de * |
