Notes. UD, GD and PS stand for uniform disk, Gaussian disk and point source, respectively. ρ and θ stand for the separation and position angle of the secondary, respectively. The wavelength-dependent parameters are provided for three selected wavelengths and the achromatic parameters (UD diameter, GD FWHM, and PS position) are presented separately.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
