Sampled PSFs
Sampled PSF models
Ideally, rather than relying on a single synthetic PSF, multiple Point Spread Functions are provided instead, by means of carefully selected samples. These samples should take the form of. isolated stars on an even background that do not over expose, nor are too dim. Ideally, these samples are provided for all areas across the image, so that the module can analyse and model how the PSF changes from pixel-to-pixel for all areas of the image.
