Chem-I-Calc: Chemical Information Calculator

Chem-I-Calc: Chemical Information Calculator [/b] Abstract : Chem-I-Calc evaluates the chemical information content of resolved star spectroscopy. It takes advantage of the Fisher information matrix and the Cramér-Rao inequality to quickly calculate the Cramér-Rao lower bounds (CRLBs), which give t...

ART: A Reconstruction Tool

ART: A Reconstruction Tool [/b] Abstract : ART reconstructs log-probability distributions using Gaussian processes. It requires an existing MCMC chain or similar set of samples from a probability distribution, including the log-probabilities. Gaussian process regression is used for interpolating th...

shear-stacking: Stacked shear profiles and tests based upon them

shear-stacking: Stacked shear profiles and tests based upon them [/b] Abstract : shear-stacking calculates stacked shear profiles and tests based upon them, e.g. consistency for different slices of lensed background galaxies. The basic concept is that the lensing signal in terms of surface mass den...

PyROA: Modeling quasar light curves

PyROA: Modeling quasar light curves [/b] Abstract : PyROA models quasar light curves where the variability is described using a running optimal average (ROA), and parameters are sampled using Markov Chain Monte Carlo (MCMC) techniques using emcee (ascl:1303.002). Using a Bayesian approach, priors c...
