\maketitle

\begin{abstract}
The \software{hep-float} package redefines some \hologo{LaTeX} float placement defaults and defines convenience wrappers for floats.
\end{abstract}

The \software{hep-float} package can be loaded with "\usepackage{hep-float}".

\DescribeEnv{figure}
\DescribeEnv{table}
Automatic float placement is adjusted to place a single float at the top of pages and to reduce the number of float pages, using the \hologo{LaTeX} macros.

"\setcounter{bottomnumber}{0}" \hfill no floats at the bottom of a page (default 1) \\
"\setcounter{topnumber}{1}" \hfill a single float at the top of a page (default 2) \\
"\setcounter{dbltopnumber}{1}" \hfill same for full widths floats in two-column mode \\
"\renewcommand{\textfraction}{.1}" \hfill large floats are allowed (default 0.2)\\
"\renewcommand{\topfraction}{.9}" \hfill (default 0.7) \\
"\renewcommand{\dbltopfraction}{.9}" \hfill (default 0.7) \\
"\renewcommand{\floatpagefraction}{.8}" \hfill float pages must be full (default 0.5)

The most useful float placement is usually archived by placing the float \emph{in front} of the paragraph it is referenced in first.
\DescribeMacro{manualplacement}
Additionally, manual float placement can be deactivated using the "manualplacement" package option.

\DescribeMacro{\raggedright}
The float environments have been adjusted to center their content.
The usual behaviour can be reactivated using "\raggedright".

} \label{tab:table}
\end{table}

\DescribeEnv{panels}
\DescribeMacro{\panel}
The "panels" environment makes use of the \software{subcaption} package \cite{subcaption}.
It provides sub-floats and takes as mandatory argument either the number of sub-floats (default~2) or the width of the first sub-float as fraction of the "\linewidth".
Within the "\begin{panels}"\oarg{vertical alignment}\marg{width} environment the "\panel" macro initiates a new sub-float.
In the case that the width of the first sub-float has been given as an optional argument to the "panels" environment the "\panel"\marg{width} macro takes the width of the next sub-float as mandatory argument.
The example code is presented in \cref{tab:panels}.
\DescribeMacro{\panelhspace}
\DescribeMacro{\panelvspace}
The spacing between the panels can be adjusted by adjusting the "\panelvspace" in terms of a "\linewidth" fraction "\renewcommand{\panelhspace}"{fraction} and the "\panelvspace" in terms of a length "\renewcommand{\panelvspace}"\marg{length}.

\DescribeEnv{tabular}
The \software{booktabs} \cite{booktabs} and \software{multirow} \cite{multirow} packages are loaded enabling publication quality tabulars such as in \cref{tab:booktabs}.

\DescribeMacro{\graphic}
\DescribeMacro{\graphics}
The \software{graphicx} package \cite{graphicx} is loaded and the "\graphic"\oarg{width}\marg{figure} macro is defined, which is a wrapper for the "\includegraphics"\marg{figure} macro and takes the figure width as fraction of the "\linewidth" as optional argument (default~1).
If the graphics are located in a sub-folder its path can be indicated by "\graphics"\marg{subfolder}.
