From the measurements of the temperature-dependent magnetic penetration depth ${\\lambda}$, the superconducting order parameter exhibits nodeless pairing, which fits best to an anisotropic $s$-wave gap symmetry. We further show that the $T_{\\rm c}$/$\\lambda^{-2}$ ratio is comparable to that of unconventional superconductors.
