GollumFit is an open-source framework for performing binned-likelihood, high-energy neutrino telescope analyses. It fits Monte Carlo simulations to observed data across a large number of nuisance parameters — detector efficiencies, neutrino fluxes, ice properties, and hadronic interactions — using the LBFGSB minimization algorithm.
Full documentation, including installation instructions, code structure, and usage examples, is available at:

See the installation guide to build from source or run via container, and the examples for common analysis workflows.
