19 | // *** 07 September 2006 | |
20 | // This class allows to fill a really general grid in (eta,phi) | |
21 | // Two types of grid can be setted : | |
22 | // if fGrid==0 -> the complete acceptance of a rectangular detector acceptance is filled | |
23 | // if fGrid==1 -> the previous grid - an other rectangular detector acceptance is filled | |
24 | // A (eta,phi(rad)) position can be extracted from an index value without looping over all entries | |
25 | // An index position can be extracted from a (eta,phi(rad)) position without looping over all entries | |
26 | // | |
27 | // How to run it : | |
28 | // > AliJetGrid *grid = new AliJetGrid((NbinPhi-1),(NbinEta-1),PhiMin,PhiMax,EtaMin,EtaMax); | |
29 | // > grid->SetGridType(...); // 0 or 1 for the moment | |
30 | // > grid->SetMatrixIndexes(); | |
31 | // > grid->SetIndexIJ(); | |
