threepoint models the third-order aperture statistics, the natural components of the shear three-point correlation function and the covariance of third-order aperture statistics. Third-order weak lensing statistics extract cosmological information in the non-Gaussianity of the cosmic large-scale structure, making them a promising tool for cosmological analyses.
OneCovariance calculates the covariance matrix of photometric large-scale structure surveys. It can produce the covariance matrix for all the 2-point statistics used within the Kilo-Degree-Survey (KiDS), including configuration space statistics, bandpowers, and COSEBIs. These observables are derived from projected Fourier space quantities. OneCovariance is flexible, in that it can read in the ingredients from a harmonic space covariance matrix and produce one of the mentioned statistics.
