than 150~words, which should be written as a single paragraph
and should not contain references and notes.

\maketitle
\section{Section heading}
A section title is styled as above, and first paragraphs after
headings are not indented. References appear in numerical
order~\cite{Raby1966,Dupont1961}. An itemized list looks like the following:
\begin{itemize}
\item the first item,
\item the second item.
\end{itemize}
You can also have an enumerated list:
\begin{enumerate}
\item the first item,
\item the second item.
\end{enumerate}
\subsection{Subsection heading}
As you see the first paragraph is not indented. References when part
of the text use the term `Ref.', for example, see
Ref.~\cite{Raby1966} and
Refs.~\cite{Appleman1959,vanBerg1965,Bryant1985,Allen1977}.
Subsequent paragraphs are indented. See Table~\ref{tab:LET} for an
example of how to display a table.
\begin{table}[h]
\begin{center}
\caption{A simple table}
\label{tab:LET}
\begin{tabular}{p{6cm}cc}
\hline\hline
\textbf{Heading} & \textbf{Result 1}
& \textbf{Result 2}\\
\hline
200 kVp X-rays total$^{a}$ & 3.25 & 1.79 \\
200 kVp X-rays (primary) & 2.60 & 1.48 \\
\hline\hline
\multicolumn{3}{l}{$^{a}$ \footnotesize Notes in tables appear as
this one here.}
\end{tabular}
\end{center}
\end{table}
\subsubsection{Subsubsection title}
\label{sec:sss}
Equation~(\ref{eq:a1}) is presented correctly:
\begin{equation}
n^k(h)= k h \frac{k}{32}~. \label{eq:a1}
\end{equation}
This is how all equations should be formatted,
including~Eqs.~(2)--(10),
%% With LaTeX use: Eqs,~(\ref{eq:a2})--(\ref{eq:a10}) syntax.
which are not shown\footnote{Footnotes are
to be used only when absolutely necessary.}.
\subsubsubsection{Subsubsubsection title}
Figure~\ref{tab:LET} is an example of how to display figures. Please
refer to figures as Figs.~2--4, etc.
%% With LaTeX use : Figs.~\ref{fig:a1}--\ref{fig:a4} syntax.
Section~\ref{sec:sss} is a cross-reference to a section.
See the document describing the CERN Yellow reports~\cite{cernrep} for more
details on how to present figures, tables, equations, and much more
with \LaTeX.
