a) A single two-dimensional Gaussian function, Eq. (B.8), with σx = σy = 1.9 and μx = μy = 0 representing a Gaussian beam of a telescope. b) Cut through the Gaussian function described in a) at half height. c) A single two-dimensional Gaussian function, with σx = σy = 1.1 and μx = 0.5 and μy = 0.9 representing a Gaussian beam of a point source. d) Cut through the Gaussian function described in c) at half height. e) Convolved Gaussian of telescope and point source as given by Eq. (B.10). f) Cut through the convolved Gaussian function described in e) at half height.
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.
