Comparison of the deconvolution with the simulated truth. Panel a: simulated true object, o. Panel b: estimated binary object, $\overline{\mathit{d}}$, applying a threshold to Panel e. Panel c: the object’s first deconvolu-tion after the estimation of the PSF core parameters, p^core. Panel d: the object’s final deconvolution after the alternate estimation of the PSF wing, p. Panel e: simulated blurred and noisy data, d. Panels f-h: model residuals, d − d^mod, for the binary object (Panel f), after the first deconvolution (Panel g) and after the final deconvolution (Panel h). Panels i–l: thrice the absolute value of the object residuals with the shifted object, 3|õ − κo^mod|, for the true object (Panel i), for the binary object (Panel j), after the first deconvolution (Panel k), and after the final deconvolution (Panel l). Intensity scale of Panels a–e, i–l: see Fig. 1b. Intensity scale of Panels f–h: see Fig. 2d. Panel m: intensity slices along the dashed coloured line of Panels a–e. Panel n: radial profiles of the true PSF (black), its closest Moffat fit (red), the PSF core estimate (blue), and the PSF wing deconvolution (green) on a logarithmic scale.
