- Update to 1.13.0
## General
* scikit-learn has been removed as an optional dependency.
[#1774]
## New Features
### photutils.datasets
* Added a make_model_image function for generating simulated
images with model sources. This function has more options and
is significantly faster than the now-deprecated
make_model_sources_image function. [#1759, #1790]
* Added a make_model_params function to make a table of randomly
generated model positions and fluxes for simulated sources.
[#1766, #1796]
### photutils.detection
* The find_peaks function now supports input arrays with units.
[#1743]
* The Table returned from find_peaks now has an id column that
contains unique integer IDs for each peak. [#1743]
* The DAOStarFinder, IRAFStarFinder, and StarFinder classes now
support input arrays with units. [#1746]
### photutils.profiles
* Added an unnormalize method to RadialProfile and CurveOfGrowth
to return the profile to the state before any normalize calls
were run. [#1732]
* Added calc_ee_from_radius and calc_radius_from_ee methods to
CurveOfGrowth. [#1733]
### photutils.psf
* Added an include_localbkg keyword to the IterativePSFPhotometry
make_model_image and make_residual_image methods. [#1756]
* Added “x_fit”, “xfit”, “y_fit”, “yfit”, “flux_fit”, and (forwarded request 1186835 from bnavigator)
