17 | * analysis task for jet flow preparation | |
18 | * | |
19 | * this task is part of the emcal jet framework and should be run in the emcaljet train | |
20 | * the following extensions to an accepted AliVEvent are expected: | |
21 | * - (anti-kt) jets | |
22 | * - background estimate rho | |
23 | * - pico tracks | |
24 | * aod's and esd's are handled transparently | |
25 | * the task will attempt to estimate a phi-dependent background density rho | |
847e45e0 | 26 | * by fitting vn harmonics to the dpt/dphi distribution |
