Abstract

Simulating a survey of fluxes and redshifts (distances) from an astrophysical population is a
routine task. popsynth provides a generic, object-oriented framework to produce synthetic
surveys from various distributions and luminosity functions, apply selection functions to the
observed variables and store them in a portable (HDF5) format. Population synthesis routines
can be constructed either using classes or from a serializable YAML format allowing flexibility
and portability. Users can not only sample the luminosity and distance of the populations,
but they can create auxiliary distributions for parameters which can have arbitrarily complex
dependencies on one another. Thus, users can simulate complex astrophysical populations
which can be used to calibrate analysis frameworks or quickly test ideas.
