What’s New in Photutils 1.10?¶
Here we highlight some of the new functionality of the 1.10 release. In addition to these changes, Photutils 1.10 includes a large number of smaller improvements and bug fixes, which are described in the full Changelog.
Reading WebbPSF Gridded PSF Models¶
The GriddedPSFModel
read
method can now
read FITS files containing ePSF grids that were generated by WebbPSF.
Minimum separation parameter for DAOStarFinder
and IRAFStarFinder
¶
An optional min_separation
keyword is now available
in the DAOStarFinder
and
IRAFStarFinder
classes. This parameter defines a
minimum separation (in pixels) for detected objects.
PSF photometry models¶
A make_psf_model
function was added for making a PSF
model from a 2D Astropy model. Compound models are also supported.
The output PSF model can be used in the PSF photometry classes. This
function replaces the deprecated prepare_psf_model
function.
GriddedPSFModel
oversampling¶
The GriddedPSFModel
oversampling can now be different
in the x and y directions. The oversampling
attribute is now stored
as a 1D numpy.ndarray
with two elements.
