frb_covariance calculates the covariance of fast radio burst (FRB) dispersion measures (DMs) induced by large-scale structure (LSS) for a list of FRBs with observed redshift and position on the sky. A worked example is included in the repository that demonstrates how to run the software.

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.
