%%% Double column output routines, 
%%% with single and double column insertions,
%%% to be positioned at page or column top, page or column bottom, page 
%%% or column center, or full page floating insertion.
%%% This code was originally based on Frank Mittlebach's multicol.sty.
%%% The concept of how to balance columns is due to Donald Knuth. The
%%% way to integrate the changed output routine into the standard LaTeX 
%%% output routine is due to Frank. 
%%% The method of making the single and double column insertions and the
%%% changes in the output routines to accomodate these features are mine.

But this change now removed to production.sty

Changed \newcommand{\footnotesize} leading from 8/9.5 to 8/9.

Increased width of two-column caption: \widecaptionwidth=35pc to 41pc for GRL

Reduced fontsize from small to footnotesize (8/9) in \tabletextfont
