calc_psf_metrics_single¶
- paarti.psf_metrics.metrics.calc_psf_metrics_single(psf, pixel_scale, oversamp=1, cut_radius=20)[source]¶
Calculate Strehl, empirical FWHM, elliptical gaussian fit FWHM, encircled energy, etc. on a single PSF image. Note, the PSF image is assumed to be normalized in MAOS style such that the peak pixel value is the Strehl value.
- psfndarray
A 2D PSF on which to calculate metrics.
