10 | // AliITSTrackleterSPDEff - find SPD chips efficiencies by using tracklets. | |
11 | // | |
12 | // This class has been derived from AliITSMultReconstructor (see | |
13 | // it for more details). It is the class for the Trackleter used to estimate | |
14 | // SPD plane efficiency. | |
15 | // The trackleter prediction is built using the vertex and 1 cluster. | |
16 | ||
17 | // | |
18 | // | |
19 | // Author : Giuseppe Eugenio Bruno, based on the skeleton of Reconstruct method provided by Tiziano Virgili | |
