Version 0.5.0

August 28th 2023

This release introduces major upgrades to the PetroFit package. Major changes include refactoring the package to make it easy to use and error estimates on Petrosian and fitted parameters. Please see the changes below and the PetroFit documentation for more information.

PetroFit Enhancements

  • Allow users to choose fitters in fit_model. #187
  • Introduce TRFLSQFitter as the default fitter. #187
  • Enable calc_uncertainties for fitting. This allows users to get paramter errors on fits. #187
  • Oversampled PSF in PSFConvolvedModel2D. #187
  • Remove CircleCI and add GitHub CI workflow. #181
  • A new option to address low signal-to-noise ratio issues when measuring r_99 by allowing the use of r_80.
    While r_80 provides good estimates of r_50 (r_e), it can sometimes result in an overestimation of r_99.
    To ensure accuracy, correction grids can be utilized to estimate r_99 from r_80. However, we maintain the
    Petrosian measurement philosophy that correction grids should be reserved for high-precision measurements.
  • Error estimates for all Petrosian Radii according to Strauss et. al 2002 Appendix A.3. #169
  • Saving/reading profiles to/from file. #169
  • Grid generation now has multi-processing support. #169
  • Moffat2D and EllipMoffat2D Deprecated. #157
  • PSFModel has been depreciated and replaced by PSFConvolvedModel2D. #156

General bug fixes and small changes

  • Remove DecisionTreeRegressor. #192
  • Change sklearn to scikit-learn. #174 by @astro-nova
  • Remove kernel key word from segmentation functions since PhotUtils no longer accepts them. #169
  • order_cat moved to segmentation sub-module. #169
  • source_photometry moved to segmentation sub-module. #169
  • make_radius_list moved to utils sub-module. #169
  • Refactor: photometry.flux_to_abmag -> utils.hst_flux_to_abmag. #169
  • Refactor: Move measure_fwhm from utils to modeling.fitting. #169
  • Depreciate calculate_photometic_density. #169
  • Depreciate object_photometry, now its called radial_photometry. #169
  • Depreciate measure_fwhm. #169
  • Change the bkg_sub keywords to bg_sub to match PhotUtils. #158
  • Recenter example PSF #159
