Although Gl 581 d is no longer thought to be a planet, this example reproduces Fig. 6 in Heller et al. (2011) and validates the EqTide module. Results for the rotational period and obliquity for both the "constant-phase-lag" (CPL) and "constant-time-lag" (CTL) models are compared.

Left: Rotational period evolution for the CPL (dashed curve) and CTL (solid curve) assuming an initial rotation period of 1 day, a tidal Q of 100, and and obliquity of 23.5 degrees. Right: Same, but for obliquity.
