EPIPROD revision history

EPIPROD is a program originally written by T. E. Payerle, as my student, to calculate observables and response functions for pion electroproduction experiments. The work began in 1993 while I was on sabbatical in NIKHEF and started with an earlier program by R. W. Lourie, with corrections and considerably expanded capabilities. Version 2.3.6 was released in 1995 and is the last version with which Payerle was involved. Since then I have extensively rewritten EPIPROD and expanded its capabilities.  Eta production became available in Version 3.0, Monte Carlo event generation became available in Version 4.0, and data analysis routines became available in Version 5.0

We strongly recommend that new users begin with the most recent version available.  Brief descriptions of some intermediate versions are retained here to document development of features, but dates are only approximate.


Version 2.3.6 (March, 1995)

Final version of the pion electroproduction code by T. E. Payerle.  Among its features are:

Version 3.0 (September, 1997)

Electroproduction of pseudoscalar mesons on nucleon targets.
