SizedPSF.compare¶
giant.point_spread_functions.psf_meta:
- SizedPSF.compare(other)[source]¶
For real PSFs, this method generates how well the PSF matches another between 0 and 1, with 1 being a perfect match and 0 being a horrible match.
Typically this is evaluated as the clipped pearson product moment coefficient between the kernels of the 2 psfs.
- Parameters:
other (PointSpreadFunction)
- Return type:
float
