%  American Nuclear Society Transaction template
%  by Seth R. Johnson, based on the ANS transaction guidelines
%
% For further updates, see http://reference-man.com/projects.html#anstemplate
%
% Usage: \documentclass{anstrans}
%  Define \title and \author as usual, and also define \institute and \email .
%  For two-column tables, use the table* environment. Multiple authors should
%  look like 
%   {Seth R. Johnson \and Edward W. Larsen}
%
% v1.1.5: Increasing column separation
% v1.1.4: Added disclaimer option (thanks to Aaron Bevill)
% v1.1.3: Improved header behavior
% v1.1.2: Improved spacing for standards compliance
%         now commas separate author names
%         Added support for proper equation numbering in appendices
% v1.1.1: Figure and table captions are now flush with the left as the
%         standards specify. Now uses the ``txfonts'' package for much improved
%         Times-compatible math font.
