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](https://ui.adsabs.harvard.edu/abs/2002AJ....124.1810S/abstract) 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 + ## Version 0.4.1 *August 22nd 2022*
