V, T, TS, E and ES are Venus, Titan, Titan synchronous, Earth, and Earth synchronous conditions, respectively. $\Omega$ is the planetary rotation rate, $T_{\Omega}$ is the planetary rotation period, $T_{\rm solar}$ is the solar day, $T_{\rm orbit}$ is the orbital period, and~$a$ is the planetary radius.
