WebThe basis function methods use smooth functions which have explicit formulas and easily to be created. As our test results have shown, Moffatlets performed better in image reconstructions than Gaussianlets. This is mainly because the Moffat function is a better PSF model than the Gaussian function. WebThe Point Spread Function (PSF) of the astronomical imaging system is usually approximated by a Gaussian or Moffat function. For simplification, the astronomical imaging system is considered to be time and space invariant. This means that invariable PSF within an exposed image is assumed. If real wide-field imaging systems are …
