You could also use the function to determine where the … WebFWHM is constant regardless of star intensity. It is a good measure of sharpness. As conditions get fuzzy for seeing, focus, or guiding quality, the width spreads out in relation. The lower an FWHM value is, the better, essentially sharper, the image. A value of 2.0 or below, measured in arcseconds, is a good value for FWHM.
