20 | // reconstructed objects: Digits, RecPoints, TrackSegments and RecParticles, | |
21 | // instead of directly reading them from galice.root file. This container | |
88cb7938 | 22 | // ensures, that one reads Digits, made of these particular digits, RecPoints, |
ffa6d63b | 23 | // made of these particular RecPoints, TrackSegments and RecParticles. |
24 | // This becomes non trivial if there are several identical branches, produced with | |
d75bea67 | 25 | // different set of parameters. |
