View ArticleBayes Factors via Savage-Dickey Supermodels
We outline a new method to compute the Bayes Factor for model selection which bypasses the Bayesian Evidence. Our method combines multiple models into a single, nested, Supermodel using one or more...
View ArticleCERES: A Set of Automated Reduction Routines for Echelle Spectra
We present the Collection of Extraction Routines for Echelle Spectra (CERES). These routines were developed for the construction of automated pipelines for the reduction, extraction and analysis of...
