[texhax] Centered Caption across two columb, Left justified in one columb

[David Vannucci]

Hello All,

I am using the article class with a journals style file. If a figure caption
is over one column in a two column page it is left justified, however they
have neglected to center the caption if it is across both columns.

This is their code
\long\def\@makecaption#1#2{\vskip 8pt{\normalfont\small #1. #2\par}}

How do I modify it so that the captions are center justified for two column
figures, and remain left justified for one column.

This is the original make caption from article.cls

\long\def\@makecaption#1#2{%
  \vskip\abovecaptionskip
  \sbox\@tempboxa{#1: #2}%
  \ifdim \wd\@tempboxa >\hsize
    #1: #2\par
  \else
    \global \@minipagefalse
    \hb at xt@\hsize{\hfil\box\@tempboxa\hfil}%
  \fi
  \vskip\belowcaptionskip}
