CAMB: uninterpolated CMB Cl's

Post by Alessio Spurio » June 18 2020

Does Python CAMB perform interpolation of the CMB [math]'s calculated at certain multipoles, to obtain the [math]'s at each value [math]? Or does it compute the [math] at each multipole [math]? If it performs interpolation, is there a way to access the uninterpolated [math]'s?

They are interpolated by default. You can set CAMBparams.Accuracy.lSampleBoost = 50 to make it calculate all L without interpolation.
