Fast winds on HD 189733b


spiderman is a fast, analytical code for calculating secondary eclipses and phase curves. The code is written in C, and uses a novel radial integrator, which makes it exceptionally fast, and an ideal input to an MCMC. An arbitrary brightness distribution can be used, and planetary limb darkening can also be included.

The source code is availible at:
