170    returns an approximation of the geomagnetic flux density $B$ as described in
171    Equation~\ref{ref:MAG:EQU:5} for the given \member{latitude}.
172    The \member{longitude} parameter is currently ignored and the return value is
173    the tuple $(B_r, B_{\theta}, 0)$.

178    converts one or more (longitude,latitude) pairs to the corresponding (x,y)
179    coordinates in the \emph{Universal Transverse Mercator} (UTM) projection.
