Moffat PSF fit parameters (FWHM in the top panel, β in the bottom panel) as a function of wavelength for the two stars found in the field of CGr35. Open symbols represent outliers discarded from the fit. The linear fit of the FWHM and the mean of β are shown as black lines. The absence of points between 5800 and 5980 Å (vertical hatched yellow region) is due to the sodium notch filter when laser-assisted AO observations are acquired.
