6 * @brief Script to add a multiplicity task for the central
10 * @ingroup pwg2_forward_scripts_tasks
13 * Create the central @f$ dN/d\eta@f$ analysis task
15 * @param trig Trigger to use
16 * @param vzMin Smallest @f$ v_z@f$
17 * @param vzMax Biggest @f$ v_z@f$
18 * @param useCent Whether to use the centrality or not
19 * @param scheme Normalisation scheme
20 * @param cutEdges Whether to cut edges when rebinning
21 * @param mcanalysisfilename Take final MC corrections from this - if present
23 * @return Newly created and configured task
25 * @ingroup pwg2_forward_dndeta
