42 * This macro displays geometrical information related to the
43 * hits, digits and rec points (or V2 clusters) in ITS.
44 * There are histograms that are not displayed (i.e. energy
45 * deposition) but that are saved onto a file (see below)
49 * Int_t evesel: the selected event number. It's =0 by default
51 * Options: Any combination of:
52 * 1) subdetector name: "SPD", "SDD", "SSD", "All" (default)
53 * 2) Printouts: "Verbose" Almost everything is printed out:
54 * it is wise to redirect the output onto a file
55 * e.g.: .x AliITSGeoPlot.C("All+Verbose") > out.log
56 * 3) Rec Points option: "Rec" ---> Uses Rec. Points (default)
58 * 4) ClustersV2 option: "ClustersV2" ---->Uses ClustersV2
59 * otherwise ---->uses hits and digits only
61 * .x AliITSGeoPlot(); (All subdetectors; no-verbose; no-recpoints)
62 * .x AliITSGeoPlot("SPD+SSD+Verbose+Rec");
64 * filename: It's "galice.root" by default.
65 * isfastpoints: integer. It is set to 0 by defaults. This means that
66 * slow reconstruction is assumed. If fast recpoint are in
67 * in use, isfastpoints must be set =1.
69 * OUTPUT: It produces a root file with a list of histograms
71 * WARNING: spatial information for SSD/DIGITS is obtained by pairing
72 * digits on p and n side originating from the same track, when
73 * possible. This (mis)use of DIGITS is tolerated for debugging
74 * purposes only !!!! The pairing in real life should be done
75 * starting from info really available...
77 * COMPILATION: this macro can be compiled.
78 * 1) You need to set your include path with
79 * gSystem->SetIncludePath("-I- -I$ALICE_ROOT/include -I$ALICE_ROOT/ITS -g");
80 * 3) If you are using root instead of aliroot you need to
81 * execute the macro loadlibs.C in advance
82 * 4) To compile this macro from root (or aliroot):
83 * --- .L AliITSGeoPlot.C++
84 * --- AliITSGeoPlot();
86 * M.Masera 14/05/2001 18:30
87 * Last rev. 31/05/2004 14:00 (Clusters V2 added) E.C.
