Nature of problem:
This program is concerned with the phenomenological analysis and the display via both the printer and graph plotter of high-energy single- particle-inclusive production reaction observables.

Solution method:
The program can be run under either the fixed t or the fixed M**2 modes when calculating differential cross sections with that for fixed t being integrated over the t-bin by 8-point Gaussian quadrature. Total cross sections can be calculated using repeated 48-point Gaussian quadrature. In addition, effective trajectories and density matrix elements can be calculated. The results of all these types of calculation can be plotted with the inclusion of the graph plotting package APLOT. The program is compatible with MINUIT and this combination has been used to perform minimization.

Restrictions:
The number of data points considered cannot exceed 500 in general. In the case where density matrix data or effective trajectory data is to be read in the number of data points cannot exceed 100. This is purely a dimensional requirement and can be altered. If density matrices are to be calculated the final detected particle must have spin less than 5/2.

Running time:
The test run took 72.2 s (of which 32.7 s was compilation time). A recent minimization calculation in which the program was used, 400 passes minimizing three parameters on 28 data points took 184 s.

Nature of problem:
This adaptation involves the phenomenological analysis and display (via printer and graph plotter) of high-energy backward inclusive single- particle production cross sections.

Solution method:
The program can be run under either the fixed t or the fixed M**2 modes for calculating differential cross sections. In the fixed t mode the t-bin is integrated over by 8-point Gaussian quadrature. The results are plotted by using the graph plotting package APLOT and POLAR PLOT AND IMPROVEMENTS. The program is compatible with the MINUIT minimization system.

Restrictions:
The number of inclusive cross section data points cannot exceed 500.

Running time:
The test run took 42.8 s(of which 23.8 s was compilation time).
