Original 2004 distribution completely replaces ALL earlier versions of the codes.

PREPRO 2004 can process all current ENDF/B-VI evaluations and

is designed to handle new ENDF/B-VII evaluations.

Corrected ERROR in SIGMA1 (Doppler broadening code).

This only effects very large output sections; over 120,000 energy points.

The latest version is identified as SIGMA1 2005-1.

Updated RECENT (Resonance reconstruction code)

to allow energy dependent scattering radius

for all resolved and unresolved resonance formalisms

(previous only allowed for single or multi-level Breit-Wigner formalism).

Also corrected energy dependent scattering radius output format.

The latest version is identified as RECENT 2005-1.
