% History
% Prepared by Rick Zaccone <zaccone@bucknell.edu> on 6/3/91.
% Modified by Adrian F Clark <alien@uk.ac.essex> 11-Jan-1992.

% Modified by Guenter Milde <G.Milde@physik.tu-dresden.de>  
%   August 1, 2001
%  Convert to LaTex2e class and added option a4paper
% Modified by Ken Hanson <kmh@lanl.gov>  August 29, 2001
%  Update SPIE format, including new text field: 6.75 in by 8.75 in
%  citesort.sty embedded to facilitate concatenation of citations.
%  However, citesort may lead to problems when used with babel, 
%   in which case it should be removed from this file.
% 2.70 Modified by Ken Hanson <kmh@lanl.gov>  August 29, 2002
%  Remove tabular in maketitle to properly handle long author list.
%  Use of \and in \author{} will start new line after inserting a
%    blank line.
%  Remove a4 option, leaving standard a4paper option in place.
%  Remove \hoffset and \voffset commands.  Defaults are again zero.
% 2.71 Modified by Ken Hanson <kmh@lanl.gov>  Sept. 18, 2002
%  Correct short figure caption format, replacing : with .  Thanks Mats.
% 2.8 Modified by Ken Hanson <kmh2@lanl.gov>  July 16, 2003
%  Margins changed to match SPIE's new specs.
% 2.9 Modified by Ken Hanson <kmh@lanl.gov>  January 23, 2006
%  Fixed bug; CMR fonts used for title with times package. Moved text 
%  slightly for A4 paper at suggestion of Markus Knauer.
% 3.00 Modified by Ken Hanson <kmh@lanl.gov>  March 5, 2006
%  Proper sized font for title and section headings for times package 
%  and other fonts. Use latest cite.sty for citations instead of 
%  imbedded code. Beware of incompatabilities with Babel and hyperref.
% 3.10 Modified by Ken Hanson <kmh@lanl.gov>  March 16, 2006
%  For title fonts, scale CMR fonts from 12pt, instead of 17pt
% 3.20 Modified by Ken Hanson <kmh@lanl.gov>  April 17, 2007
%  Small format revisions to match SPIE specifications

% Usage:
% \documentclass[]{spie}
% \documentclass[a4paper]{spie}  %% use this for A4 paper
%
% This style file does not automatically implement all the formatting
%  required for an SPIE manuscript.  The user must make a few 
%  manual adjustments For proper formatting, such as:
% 1. Title and subsubsection should be in lower case 
%    except for the first letter and proper nouns or acronyms
% 2. Subsection headings should be capitalized as for book titles
% 3. Format authors as follows
%    \author{author1\supit{a}, author2\supit{b}, and author3\supit{c} \skiplinehalf
%            \supit{a}affiliation1\\
%            \supit{b}affiliation2\\
%            \supit{c}affiliation3
%           }
%%%  Note: \skiplinehalf and \supit{} are defined in this class
% 4. Remember to reset footnote counter after nine footnotes with
%    \footnote[1]{Your footnote text goes here.}
