Notes. Each row represent one of 50 simulated test data sets, as described in Appendix D.1. The first two columns show the flux density and diameter used to generate a model of an optically thin shell. The remaining columns show the values recovered by fitting. Dashes (–) indicate no fit was attempted since source was too weak.
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.
