Detailed Description

Class that contains the central multiplicity data per event

This class contains a histogram of

\[ \frac{d^2N_{ch}}{d\eta d\phi}\quad, \]

as well as a trigger mask for each analysed event.

The eta acceptance of the event is stored in the underflow bins of the histogram. So to build the final histogram, one needs to correct for this acceptance (properly weighted by the events), and the vertex efficiency. This simply boils down to defining a 2D histogram and summing the event histograms in that histogram. One should of course also do proper book-keeping of the accepted event.
