Software using DerivKit#

DerivKit is used as a dependency or internal component in the following external software and analysis pipelines:

Augur

A DESC forecasting and inference validation tool that generates synthetic datasets and performs parameter inference using either full MCMC or second-order derivative–based Fisher matrix forecasts. DerivKit is used internally for derivative-based Fisher forecasts.

COCOA

A cosmological analysis framework that integrates CosmoLike within the Cobaya inference engine, enabling forecasts and multi-probe analyses for surveys such as DES, LSST, and the Roman Space Telescope. COCOA provides a containerized workflow for reproducible inference, ensuring consistent compiler and library environments across platforms. DerivKit is used internally for derivative-based forecasting and Fisher matrix calculations.
