TYP is aone-character variable. If it is set equal to ‘S’, only secondary particles will be histogrammed. If it is set equal to ‘P’, thenonly primary particles will be histogrammed. For no discrimination between S-econdary and P-rimary particles, TYP =‘Q’ must be used.The dimensions of the histogram (number of lines and columns) may be modified. It can be normalized with NORM = 1,to avoid saturation.Histograms are indexed with the £ parameter . This allows making independent histograms of the same coordinate atseveral spots in a structure. This is also useful when piling up problems in an input data file (see also £ RESET). is inthe range 1-5.If REBELOTE is used, the statistics on the qNPASS runs in the structure will add up.IMAGE[S][Z]: Localization and size of vertical waistsSee FOCALE[Z].
