Performance analysis of the improved seeing limited mode for the Euro50
This paper presents an analysis of the point-spread functions (PSFs),which may be expected in the so-called improved seeing limited mode forthe Euro50 (Extremely large telescope with a 50 m aperture). This modecomprises adaptive control of the deformable secondary mirror of theaplanatic Gregorian telescope configuration using guide stars in a widefield. I may result in efficient compensation of tu
