Notes. σr is the random noise between the spectral channels, σsys,s is the short-term systematic uncertainty, and σsys,l is the long-term systematic uncertainty. For visibilities and correlated fluxes, absolute and relative errors are given, respectively. The methods to estimate the uncertainties are explained in Appendix B.
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.
