% Astronomy thesis DOCUMENT STYLE for LaTeX2e
%
% Created: 1991: Siebers
%
% Modification History - 
%
%    July 1996, Eric Jensen -
%	Totally overhauled the style.  It was based on the Latex
%	``book'' style (and still is).  Before the whole file was
%	basically a copy of the Latex 2.09 book.sty file, with a few
%	things changed here and there.  Now we load the Latex2e book
%	class at the beginning, and then change only those things which
%	need to be changed (which turns out to be not very much).  A
%	modified version of the AASTeX style is loaded which defines
%	all of the commands and environments used there.
%
%	The ``thesis'' style now can be invoked with various options,
%	including type sizes (10pt, 11pt, 12pt), and with various
%	margins: ``draft'' gives smaller margins and line spacing,
%	suitable for handing to your committee but without using a
%	whole ream of paper; ``final'' conforms to the grad school
%	margin requirements and is suitable for the final copy.
%	Default is \documentclass[12pt,final]{thesis}.
%
%    July 1996, Andrea Cox:
%	Added a \fixspacing command you can use if you want to guarantee
%	  single-spaced figure and table captions in your final draft.
%	  Insert this command within the caption environments (see below).
%	Redefined the table spacing within the \draftsize and \finalsize
%	  commands, to ensure single-spacing of the table rows.  (See the
%	  "arraystretch" option.)

% The next two options, ``draft'' and ``final'' determine how big the
% margins are.  ``Final'' is the default.  Their processing is deferred
% to the end of the class so that the ``book'' class below doesn't step
% on the definitions.

% Use the draft option for printing to save paper when you don't have
% to generate a copy that meets grad school requirements.
\DeclareOption{draft}{\AtEndOfClass{\draftsize}}

% The ``final'' option will pass the Margin Lady.
\DeclareOption{final}{\AtEndOfClass{\finalsize}}

% If they don't specify "draft" or "final", use final for the default:

\ProcessOptions

% Construct a point-size option name (e.g. ``12pt'') based on the
% options specified above:

\def\ptoption{\@myptsize pt}

% Load the Latex2e ``book'' class to get the basic definitions:
\LoadClass[oneside,\ptoption]{book}

% Also input a modified version of the AAS MS style to add various

\input{thesis_aasms.sty}


% Fix the "chapter" command so it doesn't change the page style for
% the first page of each chapter (took out "\thispagestyle{plain}"

% Slight redefinition of two commands which change the size of the chapter

\newcommand\chaptertitlesize{\LARGE}

% This controls the size of the heading for table of contents, list
% of figures, and list of tables.
\newcommand\toctitlesize{\LARGE}

% Also give the user the opportunity to set the page footer and header
% from within the document.  By default, the header does the page
% numbering, but you might want to put extra info in the footers.  One
% example: \setfoot{\tiny \hss DRAFT \today\hss} will create a footer
% with the word "DRAFT" and today's date in small print centered at the
% bottom of each page - handy when dealing with multiple drafts and
% trying to remember what you printed when.

%
% The page style 'foo' is defined by defining the command \ps@foo.  This
% command should make only local definitions.  There should be no stray
% spaces in the definition, since they could lead to mysterious extra
% spaces in the output.
%
% The \ps@... command defines the macros \@oddhead, \@oddfoot,
% \@evenhead, and \@evenfoot to define the running heads and
% feet---e.g., \@oddhead is the macro to produce the contents of the
% heading box for odd-numbered pages.  It is called inside an \hbox of
% width \textwidth.
%
% To make headings determined by the sectioning commands, the page style
% defines the commands \chaptermark, \sectionmark, ... , where
% \chaptermark{TEXT} is called by \chapter to set a mark, and so on.
% The \...mark commands and the \...head macros are defined with the
% help of the following macros.  (All the \...mark commands should be
% initialized to no-ops.)
%
% MARKING CONVENTIONS:
% LaTeX extends TeX's \mark facility by producing two kinds of marks
% a 'left' and a 'right' mark, using the following commands:
%     \markboth{LEFT}{RIGHT} : Adds both marks.
%     \markright{RIGHT}      : Adds a 'right' mark.
%     \leftmark  : Used in the \@oddhead, \@oddfoot, \@evenhead or \@evenfoot
%                  macro, gets the current 'left'  mark.  Works like TeX's
%                  \botmark command.
%     \rightmark : Used in the \@oddhead, \@oddfoot, \@evenhead or \@evenfoot
%                  macro, gets the current 'right'  mark.  Works like TeX's
%                  \firstmark command.
% The marking commands work reasonably well for right marks 'numbered
% within' left marks--e.g., the left mark is changed by a \chapter command and
% the right mark is changed by a \section command.  However, it does
% produce somewhat anomalous results if two \bothmark's occur on the same page.
%
% Commands like \tableofcontents that should set the marks in some page styles
% use a \@mkboth command, which is \let by the pagestyle command (\ps@...)
% to \markboth for setting the heading or \@gobbletwo to do nothing.

\mark{{}{}}   % Initializes TeX's marks
