Basic Spectral Corrections

This module implements extinction (reddening) and redshift corrections for astronomical spectra, using JAX for differentiable, batched execution.

unred(wave, flux, ebv, R_V=3.1, LMC2=False, AVGLMC=False): Apply Galactic extinction correction to spectra using the Cardelli et al. (1989) extinction law with optional LMC parameterizations. Based on the code [https://github.com/sczesla/PyAstronomy/blob/93f6f0668d6b5aa77d281981e13ba1bf6ded38cd/src/pyasl/asl/unred.py#L4]
deredshift(spectra, z): Apply redshift correction to spectra by transforming both the wavelength and flux/error channels.
