Features

The main functionality of Voiager includes the following steps:

• Reading of tracer and void catalogs (based on VIDE)

• Generation of random catalogs (based on healpy)

• Estimation of void-galaxy cross-correlation functions (based on scipy k-d trees)

• Projection and deprojection along the line of sight (based on PyAbel)

• Estimation of covariances (based on jackknife resampling)

• Models and likelihood functions (based on linear theory and Gaussian statistics)

• Maximization of likelihoods (based on scipy.optimize)

• Sampling of likelihoods (based on emcee)

• Plotting of summary statistics and results (based on matplotlib and GetDist)
