-/****************************************************************************
- *          Legacy comparison macro, adapted to the upgraded ITS.           *
- *                                                                          *
- *               Creates list of "trackable" tracks,                        *
- *             calculates efficiency, resolutions etc.                      *
- *  The ESD tracks must be in an appropriate state (kITSin or kITSrefit)    *
- *                                                                          *
- * Before running, load the ITSU libraries:                                 *
- *  gSystem->Load("libITSUpgradeBase");gSystem->Load("libITSUpgradeRec");   *
- *                                                                          *

- *          A standalone comparison macro for the upgraded ITS.             *
- *                                                                          *
- *               Creates list of "trackable" tracks,                        *
- *             calculates efficiency, resolutions etc.                      *
- *  The ESD tracks must be in an appropriate state: kITSrefit               *
- *                                                                          *
- *          The efficiency and resolutions are calculated                   * 
- *   wrt "primary-like" pions within the acceptance tan(lambda)~[-1,1]      *
- *        and for tracks having all 7 clusters correctly assigned.          *
- *                                                                          *
- * Before running, load the ITSU libraries:                                 *
