10 | // High Level Trigger ITS vertexer | |
11 | // This class is a fast version of the off-line AliITSVertexerZ. | |
12 | // The two main differences with respect to the off-line vertexer | |
13 | // are the splitting of the clusters in phi bins and the filling | |
14 | // of local arrays instead of root histograms. | |
15 | // | |
