275a301c | 17 | // AliITSTrackleterSPDEff - find SPD chips efficiencies by using tracklets. |
84161aec | 18 | // |
19 | // This class has been developed from AliITSMultReconstructor (see | |
20 | // it for more details). It is the class for the Trackleter used to estimate | |
21 | // SPD plane efficiency. | |
275a301c | 22 | // The trackleter prediction is built using the vertex and 1 cluster. |
23 | // | |
84161aec | 24 | // |
