19/// \class AliMUONRejectList
20///
21/// Object to hold the probability to reject elements during reconstruction.
22///
23/// Those elements are either channels, manus,
24/// bus patches, detection elements, or all the four.
25/// (we do not consider the next level, chamber, because if a full
26/// chamber is missing, we assume we'll remove that run from the
27/// list of usable runs anyway).
28///
29/// The probability of rejection can be different from 0.0 or 1.0 only for
30/// simulations, in which case it means that :
31/// - this object was created from inspection of real data occupancy maps + ad-hoc rejections over
32/// several runs
33/// - the probability then reflects the chance a given element was useable
34/// during data taking. For instance, if one DE has a probability of 0.8, it means
35/// it was on (or correctly behaving during data taking) only for 20% of the
36/// events.
