  We extract $\eta$-$\eta^\prime$ mixing angle and the ratios of decay
constants of light pseudoscalar mesons $\pi^0$, $\eta$ and $\eta^\prime$ using
recently available BaBar measurements on $\eta$-photon and $\eta^\prime$-photon
transition form factors and more accurate experimental data for the masses and
two-photon decay widths of the light pseduoscalar mesons.
