PSFs and OTF profiles used for deconvolution. Top: cut of the PSFs and the reference PSF. The PSF estimated with by Conan et al. (1998) is shown with a blue dashed line, the PSF estimated with the elliptical model is shown with a red solid line, and the reference PSF obtained after the observation is shown as a black dotted line. Bottom: cut of the OTFs and the reference OTF. The OTF estimated by Conan et al. (1998) is shown as a blue dashed line, the OTF estimated with the elliptical model is shown as a red solid line, and the reference OTF obtained after the observation is shown as a black dotted line.
