d599d913 20// This is a TTask that made the calculation of the Time zero using TOF.
7aeeaf38 21// Description: The algorithm used to calculate the time zero of
22// interaction using TOF detector is the following.
23// We select in the MonteCarlo some primary particles - or tracks in
24// the following - that strike the TOF detector (the larger part are
25// pions, kaons or protons).
26// We choose a set of 10 selected tracks, for each track You have the
27// length of the track when the TOF is reached (a standard TOF hit
28// does not contain this additional information, this is the reason
29// why we implemented a new time zero dedicated TOF hit class
30// AliTOFhitT0; in order to store this type of hit You have to use the
31// AliTOFv4T0 as TOF class in Your Config.C. In AliTOFv4T0 the
32// StepManager was modified in order to fill the TOF hit branch with
33// this type of hits; in fact the AliTOF::AddT0Hit is called rather
34// that the usual AliTOF::AddHit), the momentum at generation (from
35// TreeK) and the time of flight given by the TOF detector.
36// (Observe that the ctor of the AliTOF class, when the AliTOFv4T0
37// class is used, is called with the "tzero" option: it is in order
38// create the fHits TClonesArray filled with AliTOFhitT0 objects,
39// rather than with normal AliTOFhit)
40// Then Momentum and time of flight for each track are smeared
41// according to known experimental resolution (all sources of error
42// have been token into account).
43// Let consider now only one set of 10 tracks (the algorithm is the
44// same for all sets).
45// Assuming the (mass) hypothesis that each track can be AUT a pion,
46// AUT a kaon, AUT a proton, we consider all the 3 at 10 possible
47// cases.
d599d913 48// For each track in each (mass) configuration
7aeeaf38 49// (a configuration can be
50// e.g. pion/pion/kaon/proton/pion/proton/kaon/kaon/pion/pion)
51// we calculate the time zero (we know in fact the velocity of the
52// track after the assumption about its mass, the time of flight given
53// by the TOF, and the corresponding path travelled till the TOF
54// detector). Then for each mass configuration we have 10 time zero
55// and we can calculate the ChiSquare for the current configuration
56// using the weighted mean over all 10 time zero.
57// We call the best assignment the mass configuration that gives the
58// minimum value of the ChiSquare.
59// We plot the weighted mean over all 10 time zero for the best
60// assignment, the ChiSquare for the best assignment and the
61// corresponding confidence level.
62// The strong assumption is the MC selection of primary particles. It
63// will be introduced in the future also some more realistic
64// simulation about this point.
0e46b9ae 65//
d599d913 66// Use case:
67// root [0] AliTOFT0 * tzero = new AliTOFT0("galice.root")
68// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
69// root [1] tzero->ExecuteTask()
70// root [2] tzero->ExecuteTask("tim")
71// // available parameters:
72// tim - print benchmarking information
7aeeaf38 73// all - print usefull informations about the number of
74// misidentified tracks and a comparison about the
75// true configuration (known from MC) and the best
d599d913 76// assignment
