21 | * Class that contains the forward multiplicity data per event | |
22 | * | |
23 | * This class contains a histogram of | |
24 | * @f[ | |
25 | * \frac{d^2N_{ch}}{d\eta d\phi}\quad, | |
26 | * @f] | |
27 | * as well as a trigger mask for each analysed event. | |
28 | * | |
29 | * The eta acceptance of the event is stored in the underflow bins of | |
30 | * the histogram. So to build the final histogram, one needs to | |
31 | * correct for this acceptance (properly weighted by the events), and | |
32 | * the vertex efficiency. This simply boils down to defining a 2D | |
33 | * histogram and summing the event histograms in that histogram. One | |
34 | * should of course also do proper book-keeping of the accepted event. | |
