Release to accompany submitted paper. Includes a new plotting module, demonstrations of MPI usage with dynesty, and small bugfixes.

v0.4.0

  • New models.SpecModel class that handles much of the conversion from FSPS spectra to observed frame spectra (redshifting, smoothing, dimming, spectroscopic calibration, filter projections) internally instead of relying on source classes.
  • The SpecModel class enables analytic marginalization of emission line amplitudes, with or without FSPS based priors
  • A new mixture model option in the likelihood to handle outlier points
  • A noise model kernel for photometric calibration offsets.
  • Rename mean_model to predict (old method kept for backwards compatibility)
  • Some fixes to priors and optimization
  • Python3 compatibility improvements (now developed and tested with Python3)

v0.3.0

New UI, based on argparse command line options and a high level fit_model function

  • new prospector_parse module that generates a default argument parser

  • importable default probability function as fitting.lnprobfn

  • new high level fit_model method that can use emcee, dynesty, or optimization algorithms

  • documentation and new notebook reflect UI changes
