Luminosity functions and photometric corrections toolkit.
Project description
LFKit
LFKit is a modular Python toolkit for luminosity function modeling, photometric corrections, and related utilities for cosmological analyses.
It is designed to provide reusable building blocks for working with luminosity functions, magnitude conversions, k-corrections, e-corrections, and photometric response handling in a clear and extensible way.
Features
LFKit currently includes tools for:
- luminosity function modeling
- Schechter and evolving luminosity function utilities
- magnitude and luminosity conversions
- k-corrections and e-corrections
- photometric response and filter-related helpers
- interpolation, validation, and general utility functions
The package is intended to stay modular, so components can be used independently or combined into larger analysis pipelines.
