To do list

1) perform the offline analysis on the hits/fastOr, selecting only the events having a fired hit and looking at the presence of the correlated fastOr signal in the same event or the previous one, two three event(s) [Fabio]
2) perform systematically, the comparison between the tracklet distribution vs phi for data and MC, in order to verify if the discrepancies between the two are exactly coincident with the chips affected bye the “MEB problem”. The x axis has to be shown in chips, not in phi. [Annalisa]
    —> furthermore, one has to understand which kind of event selection is applied because the MC could not take into account the pile-up
3) make clear in the excel table the information on the topology of the chips affected by the MEB problem [Domenico]
4) activate in the DCS the storage of the informations of trigger for the chip, in order to check if the chips with MEB problem are more noisy then the other [Sergey]
5) build two plot where to store, respectively, the mean number of hits per half-stave or chip and the mean number of fastOr per half-stave or chip to have a fast idea on possible not standard behaviour of the half-staves affected by the problem [Fabio/Domenico]
