A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

The code SIGMA1 Doppler broadens evaluated cross sections in the ENDF/B format. The code can be applied only to data that vary as a linear function of energy and cross section between tabulated points. This report describes the methods used in the code and serves as a user's guide to the code. 6 figures, 2 tables.

The computer code LINEAR converts evaluated cross sections in the ENDF/B format into a form that can be defined by applying linear--linear interpolation to energy and cross section parameters. The code also thins those sections already in that form. The main advantage of the code is that it eliminates the need for any subsequent code to consider anything but linear--linear data. 2 figures.
