+// (3) model_type - equals 1,2,3,4,5 or 6 so far. See comments in
+// Function dNdpty to see what is calculated.
+// The models included are:
+// = 1, Factorized mt exponential, Gaussian rapidity model
+// = 2, Pratt non-expanding, spherical thermal source model
+// = 3, Bertsch non-expanding spherical thermal source model
+// = 4, Pratt spherically expanding, thermally equilibrated
+// source model.
+// = 5, Factorized pt and eta distributions input bin-by-bin.
+// = 6, Fully 2D pt,eta distributions input bin-by-bin.
+// NOTE: model_type = 1-4 are functions of (pt,y)
+// model_type = 5,6 are functions of (pt,eta)
+// (4) reac_plane_cntrl - Can be either 1,2,3 or 4 where:
+// = 1 to ignore reaction plane and anisotropic flow,
+// all distributions will be azimuthally symm.
+// = 2 to use a fixed reaction plane angle for all
+// events in the run.
+// = 3 to assume a randomly varying reaction plane
+// angle for each event as determined by a
+// Gaussian distribution.
+// = 4 to assume a randomly varying reaction plane
+// for each event in the run as determined by
+// a uniform distribution from 0 to 360 deg.
+// (5) PSIr_mean, PSIr_stdev - Reaction plane angle mean and Gaussian
+// std.dev. (both are in degrees) for cases
+// with reac_plane_cntrl = 2 (use mean value)
+// and 3. Note: these are read in regardless
+// of the value of reac_plane_cntrl.
+// (6) MultFac_mean, MultFac_stdev - Overall multiplicity scaling factor
+// for all PID types; mean and std.dev.;
+// for trigger fluctuations event-to-evt.
+// (7) pt_cut_min,pt_cut_max - Range of transverse momentum in GeV/c.
+// (8) eta_cut_min,eta_cut_max - Pseudorapidity range
+// (9) phi_cut_min,phi_cut_max - Azimuthal angular range in degrees.
+// (10) n_stdev_mult - Number of standard deviations about the mean value
+// of multiplicity to include in the random event-to-
+// event selection process. The maximum number of
+// steps that can be covered is determined by
+// parameter n_mult_max_steps in the accompanying
+// include file 'Parameter_values.inc' which is
+// presently set at 1000, but the true upper limit for
+// this is n_mult_max_steps - 1 = 999.
+// (11) n_stdev_temp - Same, except for the "Temperature" parameter.
+// (12) n_stdev_sigma- Same, except for the rapidity width parameter.
+// (13) n_stdev_expvel - Same, except for the expansion velocity parameter.
+// (14) n_stdev_PSIr - Same, except for the reaction plane angle
+// (15) n_stdev_Vn - Same, except for the anisotropy coefficients, Vn.
+// (16) n_stdev_MultFac - Same, except for the multiplicity scaling factor.
+// (17) n_integ_pts - Number of mesh points to use in the random model
+// parameter selection process. The upper limit is
+// set by parameter nmax_integ in the accompanying
+// include file 'Parameter_values.inc' which is presently
+// set at 100, but the true upper limit for n_integ_pts
+// is nmax_integ - 1 = 99.
+// (18) n_scan_pts - Number of mesh points to use to scan the (pt,y)
+// dependence of the model distributions looking for
+// the maximum value. The 2-D grid has
+// n_scan_pts * n_scan_pts points; no limit to size of
+// n_scan_pts.
