% Instructions for authors are provided in a separate file epac.tex

% Here are some useful commands which facilitate correct formatting:
%
% To give a numerical value with units, e.g. \QTY{ 4.2 }{ MV\,n^{-1} }
% (this takes care that the units in an equation are in a roman font
%  and not in math-italic which is used for symbols, IMPORTANT!!)
%
\newcommand{\QTY}[2]{\mbox{\(#1\rm\,#2\)}}
%-----------------------------------------------------------------------
%
% To express a number in scientific notation, e.g. \Enum{1.7}{32}
\newcommand{\Enum}[2]{\mbox{\(#1\times10^{#2}\)}}
%
%-----------------------------------------------------------------------
% numerical formula e.g. \NQTY{E}{GeV} gives [E/GeV]
\newcommand{\NQTY}[2]{\mbox{$[#1/{\rm #2}]$}} % symbol with units in
%
%-----------------------------------------------------------------------
%  Expectation value or average, e.g. \EV{ x^2 } gives  &lt;x^2&gt;
\newcommand{\EV}[1]{\left\langle #1 \right\rangle}% expectation value
%
%-----------------------------------------------------------------------
% These are convenient for quoting luminosity:
\newcommand{\LUMI}[1]{\QTY{#1}{cm^{-2}s^{-1}}}
\newcommand{\LUM}[2]{\LUMI{#1\times10^{#2}}}
%
% thus a B-factory design might quote         \LUM{3.0}{33}
%-----------------------------------------------------------------------
\def\gappeq{\mathrel{ \rlap{\raise.5ex\hbox{$&gt;$}}
                      {\lower.5ex\hbox{$\sim$}}  } }
%
%  \gappeq is a compound symbol made out of a &gt; sign on top of a tilde
%  usually used to mean "greater than or approximately equal to"
%  or "vaguely greater than"  by physicists.
%  It behaves as a mathematical relation in TeX's math modes, e.g.
%  $ a \gappeq b $    in the text and
%  $$ a \gappeq b $$  as a display.
%
