CLASS Data Products - Polarized Power Spectra Quick Interpolation Software

Download Links:

Code that allows for quick interpolation between Cosmic Microwave Background polarized power spectra as a function of scalar fluctuations, tensor fluctuations, and the optical depth to reionization. This code was used in 'A Projected Estimate of the Reionization Optical Depth Using the CLASS Experiment's Sample Variance Limited E-mode Measurement', The Astrophysical Journal, Volume 863, page 121 (2018), ADS.

This code repository is available on Zenodo. Questions about the code or its use should be directed to Duncan Watts (
