     This package provides tools for radiation belt physicists to calculate the adiabiatic invariants K and L* from gridded models of Earth's magnetic field. This package supports the `T96 <https://geo.phys.spbu.ru/~tsyganenko/empirical-models/magnetic_field/t96/>`_ and `TS05 <https://geo.phys.spbu.ru/~tsyganenko/empirical-models/magnetic_field/ts05/>`_ empirical Tsyganenko magnetic field models, `SWMF <https://clasp.engin.umich.edu/research/theory-computational-methods/space-weather-modeling-framework/>`_ and `LFM <https://doi.org/10.1016/j.jastp.2004.03.020>`_ MHD simulation output, and data on an arbitrary structured grid.
