1d1ea3ce | 17 | // Add the muon tracks to the generic AOD track branch during the |
26ba01d4 | 18 | // filtering of the ESD. |
19 | // | |
20 | // Authors: R. Arnaldi 5/5/08 and L. Aphecetche January 2011 | |
21 | // | |
22 | // Note that we : | |
23 | // - completely disable all the branches that are not required by (most) the muon analyses, | |
24 | // e.g. cascades, v0s, kinks, jets, etc... | |
25 | // - filter severely the tracks (keep only muon tracks) and vertices (keep only primary -including | |
26 | // pile-up - vertices) branches | |
27 | // | |
28 | // (see AddFilteredAOD method) | |
