Rosseland And Planck Opacity Converter


Developed by Lorenzo V. Mugnai and Darius Modirrousta-Galian, the RAPOC code is the product of a collaboration between Sapienza Università di Roma, Università degli Studi di Palermo and INAF - Osservatorio Astronomico di Palermo.


RAPOC uses molecular absorption measurements (i.e. wavelength-dependent opacities) to calculate Rosseland and Planck mean opacities that are commonly used in atmospheric modelling. RAPOC is designed to be simple, straightforward, and easily incorporated into other codes. It is completely written in Python and documented with docstrings.
