PySSC is a Python implementation of the fast Sij approach to Super-Sample Covariance (SSC).
It allows to easily compute the SSC part of the covariance for most cosmological observables.
The original full-sky implementation was developed by Lacasa & Grain 2018 (arXiv:1809.05437).
The partial sky implementation was presented in Gouyou Beauchamps et al. (arXiv:2109.02308).
