Notes. Two FWHM values are given: one from an elliptical Gaussian fit to the beam, and another that is the FWHM of a Gaussian with the same solid angle as the main beam, Ωbeam. The FWHM found from the main beam solid angle is used to evaluate Ωbeam1 and Ωbeam2, which are the beam solid angles within a radius equal to this FWHM and twice this FWHM, respectively.

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.

Initial download of the metrics may take a while.
