/*******************************************************************
+
* This macro displays geometrical information related to the
+
* hits, digits and rec points (or V2 clusters) in ITS.
+
* There are histograms that are not displayed (i.e. energy
+
* deposition) but that are saved onto a file (see below)
+
*
+
* INPUT arguments:
+
*
+
* Int_t evesel: the selected event number. It's =0 by default
+
*
+
* Options: Any combination of:
+
* 1) subdetector name: "SPD", "SDD", "SSD", "All" (default)
+
* 2) Printouts: "Verbose" Almost everything is printed out:
+
* it is wise to redirect the output onto a file
+
* e.g.: .x AliITSGeoPlot.C("All+Verbose") > out.log
+
* 3) Rec Points option: "Rec" ---> Uses Rec. Points (default)
+
*
+
* 4) ClustersV2 option: "ClustersV2" ---->Uses ClustersV2
+
* otherwise ---->uses hits and digits only
+
* Examples:
+
* .x AliITSGeoPlot(); (All subdetectors; no-verbose; no-recpoints)
+
* .x AliITSGeoPlot("SPD+SSD+Verbose+Rec");
+
*
+
* filename: It's "galice.root" by default.
+
* isfastpoints: integer. It is set to 0 by defaults. This means that
+
* slow reconstruction is assumed. If fast recpoint are in
+
* in use, isfastpoints must be set =1.
+
*
+
* OUTPUT: It produces a root file with a list of histograms
+
*
+
* WARNING: spatial information for SSD/DIGITS is obtained by pairing
+
* digits on p and n side originating from the same track, when
+
* possible. This (mis)use of DIGITS is tolerated for debugging
+
* purposes only !!!! The pairing in real life should be done
+
* starting from info really available...
+
*
+
* COMPILATION: this macro can be compiled.
+
* 1) You need to set your include path with
+
* gSystem->SetIncludePath("-I- -I$ALICE_ROOT/include -I$ALICE_ROOT/ITS -g");
+
* 3) If you are using root instead of aliroot you need to
+
* execute the macro loadlibs.C in advance
+
* 4) To compile this macro from root (or aliroot):
+
* --- .L AliITSGeoPlot.C++
+
* --- AliITSGeoPlot();
