lfkit.corrections.kcorrect_from_color

kcorrect k(z) evaluation from a single color anchor.

This module provides a minimal path from a two-band color constraint to a k(z) curve. The idea is straightforward: a rest-frame color fixes a flux ratio between two bands, which constrains the mixture of kcorrect SED templates. Once the corresponding template coefficients are obtained, kcorrect can be evaluated across redshift to produce the resulting k(z).

Only a single color constraint is used. No galaxy types or population labels are introduced, and no attempt is made to infer a physical galaxy classification. The color simply defines a template mixture that is consistent with the specified flux ratio, which is then used to evaluate k(z) for the requested output response band.
