Nature of problem:
First and higher order QED and electroweak radiative corrections to the inclusive and semi-inclusive polarized deep inelastic scattering; experimental data processing.
Numerical integration of analytical formulae.
Only selective experimental cuts are possible. For O(alpha**2) order correction only leading contribution is calculated. Electroweak correction is calculated for longitudinally polarized target.
The program uses PATCHY  and MINUIT  - both part of CERNLIB.
The running time depends on the options used. For example: 1) calculation of the total QED correction takes about 4 seconds of the CPU time per one kinematical point; 2) calculation of electroweak+ O(alpha**2)+model for g2 not equal to 0 takes up to 300 seconds per one kinematical point.
