Welcome to the petitRADTRANS documentation. petitRADTRANS is a Python package for calculating transmission and emission spectra of exoplanets, at low ($$\lambda/\Delta\lambda=1000$$) and high ($$\lambda/\Delta\lambda=10^6$$) resolution, for clear and cloudy atmospheres.

Important

Scattering is currently not included for emission spectra in petitRADTRANS (but it is for the transmission spectra). We intend to migrate the scattering implementation of petitCODE to petitRADTRANS soon.
