\maketitle

\begin{abstract}
This is an example paper for manuscripts for the journal {\it Solar
Physics}. It contains the basic commands to write an article as well
as some explanations for defining equations, figures, tables,
and references.
The abstract should be no more 15 lines long.  It should summarize
the results of the article, with just enough background to clearly state the
problem being addressed.
Please do not just repeat text from the introduction and conclusion.
Please make sure that the language of the article has been reviewed by a
scientist fluent in English, or an editorial professional.
Check that all of the citations in the text are in the reference list at the
end, and that there are not extraneous references, preferably by using
$\mathrm{B{\scriptstyle{IB}} \! T\!_{\displaystyle E} \! X}$.
If you do not run a spell check on your article, do not expect
your reader to believe that you were any more careful in your science.
Choose your keywords using as guide the list provided by
\url{http://www.aip.org/pacs/pacs2010/individuals/pacs2010_regular_edition/index.html.}
\end{abstract}

\section{Introduction}

{\roaj} is an international journal covering the fields of
Astronomy, Celestial Mechanics, Stellar Astrophysics, Solar Physics and Heliosphere,
Extragalactic Astronomy and Cosmology, History of the Astronomy, Space Sciences.

{\roaj} appears twice a year in a continue series from 1991.

This Journal publishes original papers, brief reports, special communications,
theoretical and observational works. {\roaj} is the official journal of the
\emph{Romanian National Committee for Astronomy}.

\section{The latex package}
The \roaj  style could be downloaded at \url{http://aira.astro.ro/~roaj/roajstyle/}.

The package contains the files:
\begin{enumerate}
\item \textbf{roajarticle.cls} -- in this file the main code of the class resides;
\item \textbf{rrp\_font.def} -- this file defines some font related parameters;
\item \textbf{rrp\_size11.clo} -- here is the \LaTeX ~code for page layout;
\item \textbf{mynatbib.sty} -- here is the \LaTeX ~code for page the bibliography, where we made changes;
\item \textit{roaj.bst}	-- this file defines the bibliography style when
you use a (bibtex) bibliography database (.bib);
\item \textit{template.tex} -- this file contains a very short version of this documentation
\end{enumerate}

There are also packages which are loaded automatically: \textbf{textcase}, \textbf{truncate},
\textbf{color} which are used internally, \textbf{amsfonts}, \textbf{amsmath}, \textbf{amssymb}
to allow authors to use the mathematical environments provided therein rather than the normal
and limited \LaTeXe ~environments (especially \textit{eqnarray} is advised to be replaced by
environments from the AMS style - \ie  \textit{split}) and \textbf{cite} to force compression
of the citation lists. There are automatically loaded too: \textbf{url} and \textbf{lastpage} packages.

You must use in your preamble document the load of \textbf{graphicx}, \textbf{upgreek},
and \textbf{mynatbib} packages, the last one being useful to obtain the bibliography style of \roaj

\section{Editing rules}
The rules applied to edit an article are the general rules applied in latex. We point
out here only some important aspects for the \roaj style.

The figures, in \textbf{eps} format, are introduced with \emph{includegraphics}.
If you use \textbf{jpg} files, please specify the figure extension.
Use a special folder to put all your figures and refer to them
as "./folder/fig1.jpg", for instance. Refer the figure with"ref\{f1key\}".
\begin{figure}[h!]
\begin{center}
\includegraphics[width=0.9\textwidth]{f1.png}
\caption{Your caption} \label{f1}
\end{center}
\end{figure}

 \begin{table}[ht!]
 \centering
 \caption{Your caption}\label{tab1}
 {\footnotesize
 \begin{tabular}[!h]{|c|c|c|c|}
 \hline
            $z_0 = 0$ & $z_0 = L/8$ & $z_0 = L/4$ \\ \hline
            $\omega_I = -11.33 \cdot 10^{-4}$ &  $\omega_I = -11.33 \cdot 10^{-4}$  & $\omega_I = -11.33 \cdot 10^{-4}$ \\ \hline
            $\omega_I = -11.33 \cdot 10^{-4}$ & $\omega_I = -11.33 \cdot 10^{-4}$ & $\omega_I = -11.33 \cdot 10^{-4}$ \\ \hline
            $\omega_I = -11.33 \cdot 10^{-4}$ & $\omega_I = -11.33 \cdot 10^{-4}$ & $\omega_I = -11.33 \cdot 10^{-4}$ \\
 \hline
 \end{tabular}
 }
 \end{table}

The tables should be centered on the page (using "centering" command) and the reference is similar to the figures.
Please, use 9 pt fonts for the table text, like in the example.

\begin{eqnarray}\label{eqLC}
\frac{\deriv \upalpha}{\deriv t}&=& \frac{\upomega}{D} + \uptau
\end{eqnarray}

The formulas should be numbered. Please use for derived the command
\textbf{deriv } - see the preamble of this document.
For the Greek letters  inside the formulas please use the package
