Performance comparison of the four methods provided by Pandora to calculate occultation fluxes. The Mandel-Agol model (black) is the most precise, but also slowest, reference version. The hybrid model (red) uses interpolation between the small-body and the Mandel-Agol methods, and it is applicable for R_P/R_S < 0.05 to keep errors below 1 ppm. The cached algorithm (blue) is still faster, but only usable for sampling with fixed limb darkening. Finally, the small-body approximation is the fastest method, but only applicable (errors below 1 ppm) for R_P/R_S < 0.01. All methods show better performance for longer light curves due to constant factors. Numbers are given for a single core on an Intel Core-i7 1185G.
