amlc is a tool for analytically marginalizing over linear continuum parameters in models of absorption line spectra.

Installation instructions

amlc can be installed with pip:

pip install amlc --user

Dependencies

• Python 3.5+
• numpy
• scipy

Basic usage

amlc is designed for evaluating the likelihood of a spectrum given the spectrum's uncertainties, a design matrix for the continuum model, and a proposed set of absorption features:

from amlc.marginalized_likelihood import MarginalizedLikelihood

marginalized_likelihood_instance = MarginalizedLikelihood(observed_spectrum, variance_of_observed_spectrum, continuum_design_matrix)
marginalized_likelihood_instance(proposed_transmittance_model, return_logp=True)['logp']
