# kelp¶

This is the documentation for kelp, a photometric phase curve package written in Python. The source code is available on GitHub.

## Interactive demo¶

The $$h_{m\ell}$$ basis is a mathematical shorthand for describing physically-motivated temperature maps for exoplanets. Three parameters which can be tuned to fit most phase curves include the the dimensionless drag frequency $$\omega$$, the power in the $$m=\ell=1$$ spherical harmonic mode $$C_{11}$$, and the arbitrary rotational offset of the coordinate system $$\Delta\phi$$. Tweak these parameters below to see how they affect the corresponding maps and phase curves:
