resize_psf¶
- photutils.psf.matching.resize_psf(psf, input_pixel_scale, output_pixel_scale, *, order=3)[source]¶
Resize a PSF using spline interpolation of the requested order.
- Parameters:
- psf2D
ndarray The 2D data array of the PSF.
- input_pixel_scalefloat
The pixel scale of the input
psf. The units must matchoutput_pixel_scale.- output_pixel_scalefloat
The pixel scale of the output
psf. The units must matchinput_pixel_scale.- orderfloat, optional
The order of the spline interpolation (0-5). The default is 3.
- psf2D
- Returns:
- result2D
ndarray The resampled/interpolated 2D data array.
