Room temperature electron effective mass parameters of $m^{*}_{\\bot}=(0.205 \\pm 0.013)~m_0$ and $m^{*}_{\\parallel}=(0.204 \\pm 0.016)~m_0$ for polarization perpendicular and parallel to the $c$-axis, respectively, were determined. The free electron concentration was obtained as $(1.7 \\pm 0.2)\\times 10^{19}~$cm$^{-3}$.
