To test the code, we produce a light curve for a cloudless Earth in a face-on orbit with a 90$^\circ$ obliquity.

We have previously derived analytic reflected lightcurves for spherical harmonic albedo maps in the special case of a synchronously-rotating planet on an edge-on orbit (Cowan, Fuentes & Haggard 2013).

The peculiar infrared flux map of CoRoT-2b may result from westward winds due to non-synchronous rotation magnetic effects, or partial cloud coverage, that obscures the emergent flux from the planet's eastern hemisphere.

Reflected light seen by a distant observer is the product of a planet's albedo map, its host star's illumination, and the visibility of different regions.

We present a semi-analytic model atmosphere for close-in exoplanets that captures the essential physics of phase curves: orbital and viewing geometry, advection, and re-radiation.
