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.
