[ascl:2503.038] OneCovariance: Compute covariance matrices
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.
[ascl:2201.011] COWS: Cosmic web filament finder
COWS (COsmic Web Skeleton) implements the cosmic filament finder COsmic Web Skeleton (COWS). Written in Python, the cosmic filament finder works on Hessian-based cosmic web identifiers (such as the V-web) and returns a catalogue of filament spines. The code identifies the medial axis, or skeleton, of cosmic web filaments and then separates this skeleton into individual filaments.
