CalorimeterLevel2/src/CaloCore.cpp

//
//   Given a calibration and a data file this program create an ntuple with LEVEL2 calorimeter variables - Emiliano Mocchiutti
//
//   CaloCore.cxx      version 3.05 (2006-05-30)
//
//   The only input needed is the path to the directory created by YODA for the data file you want to analyze.
//
//   Changelog:
//
//   3.08 (2006-11-13): Added high energy nuclei capability and "process all events" capability.
//
//   3.04 - 3.05 (2006-05-30): Qlast and nlast are now calculated using 4 (not 8) strips aournd the shower axis. Small bug fixed.
//
//   3.03 - 3.04 (2006-05-23): Forgot to put impx and impy in the PAMELA reference system, fixed.
//
//   3.02 - 3.03 (2006-05-18): updated to be called in DarthVader. Output dimension are now in cm and in the PAMELA reference system.
//
//   3.01 - 3.02 (2006-04-21): when copying entries get size of caclone and not of ca... (shouldn't matter). Fixed increasing file dimension bug when reprocessing.
//                             Added variable planemax[2], plane of maximum energy release (x and y) in final output. Use ItoRunInfo instead of RunInfo.
//
//   3.00 - 3.01 (2006-04-14): fixed small bug in tagging the track used to determine track-related variables, put in caloprocessing the opening of parameters files, fixed
//                             small bug in fortran routines
//
//   2.01 - 3.00 (2006-04-14): almost everything has changed. Now it can process one, all or some runs, introduced the final CaloLevel2 class+methods and the 
//                             working class "CaloProcessing", linked to the preliminary tracker flight software v0r00, reads YODA unique output files,
//                             reduced the number of installed libraries, F77 programs splitted depending on the function contained, introduced the readout and
//                             processing of self-trigger events, if the tracker provides more than one track all calorimeter track-related variables are saved
//                             as many times as the number of tracks (via the TClonesArray object in the level2 rootple) and many other small changes.
//
//   2.00 - 2.01 (2006-01-26): bug: wrong calculation of baselines in some cases, fixed.
//
//   1.00 - 2.00 (2006-01-11): use TSQL ROOT classes instead of directly calling MySQL.
//
//   0.00 - 1.00 (2005-09-14): seems working.
//
//   0.00        (2005-09-09): clone of CaloLEVEL2.c .
