 uleis_idf::get_eff_geom
        Return the effective geometry factors for a ULEIS channel,
        given the time.

 Usage:
        gf = idfref -> get_eff_geom(chan, time)

 Arguments:
        chan    string/struct   The channel whose geometry is needed.
        time    double          The JD at which the geometry is
                                needed.

 Keyword:
        ending  double  output  The last JD at which this value will
                                be valid.

 Notes:
        get_geometry just returns the geometry factor of a particular
        detector, this returns the effective geometry factor taking
        into account the detectors used for a channel and their
        efficiency for that species.
