Checks

Voiager should not be used as a black box! Consistency checks are essential in order to gain confidence in the stability of your results. Below is a non-exhaustive list of possible tests to identify systematic effects. The variables in params.yaml can be used to explore those.

  • Variation of void selection cuts, especially minimum size, maximum ellipticity and core density

  • Variation of binning schemes in redshift or scale (number of bins, min and max range, etc.)

  • Consistency between different data vectors (multipoles vs. 2D correlation via variable datavec)

  • Variation of prior ranges for model parameters

  • Variation of fiducial parameter values
