only the restriction on the maximum radius \emph{R\_max}
is applied on the initial particles, while \emph{z\_min} and \emph{z\_max} are ignored.
\item{\bf /gun/vertexrelativer \emph{relativeRMaxAllowed} \emph{unit}}\\
Set maximum allowed radius of the beam relative to x0 and y0,
i.e.\ relative to the centre of the beam. This command might be useful when the beam
centre is not created at x0=y0=0, but the user wishes to restrict the beam
within a symmetric cone around x0 and y0. \\

\item{\bf /gun/boxboundarycentre \emph{xMaxSource0} \emph{yMaxSource0} \emph{xMaxSource0} \emph{unit}} \\
See below ``/gun/boxboundary''.
\item{\bf /gun/boxboundary \emph{xMaxSource} \emph{yMaxSource} \emph{xMaxSource} \emph{unit}} \\
Define a box, within which the generated particles (muons) are created.
The variables \emph{xMaxSource0}, \emph{yMaxSource0} and \emph{xMaxSource0} define the
centre of the box, the variables \emph{xMaxSource}, \emph{yMaxSource} and \emph{xMaxSource} define the
halfwidth, halfheight and halflength of the box. \\
This command can be useful for muonium excitations by laser (low energy muon beam induced by laser).\\
(Ignored by the TURTLE input).
\item{\bf /gun/kenergy \emph{kineticEnergy} \emph{unit}}\\
Set the mean kinetic energy of the initial particles (muons).\\
(Ignored by the TURTLE input).
