sys_mapping.contamination
=========================

Forward and inverse contamination model (Berlfein et al. 2024, Eq. 11–13).

Implements the three nested models (additive, multiplicative, combined),
parameter packing/unpacking for the emcee/scipy interface, and the
pixel-level two-point correction formula.

**Key paper:** `Berlfein et al. 2024 <https://arxiv.org/abs/2401.12293>`_ — see also :doc:`../methods`.
