WebThe spherical harmonics or YLMs play a special role in physics because they are appropriate for all spherically symmetric problems. The separation-constant spectrum is determined by the finite ranges of the angular coordinates. WebIn Rooney et al 2024 we rigorously derive the spherical harmonics method for reflected light and benchmark the 4-term method (SH4) against Toon et al. 1989 and two independent methods. Here, we provide the code to reproduce the analysis that compares Toon89 with the higher fidelity 4-term spherical harmonics method for reflected light calculations. productivity enhancement incentive pei 2020
