Notes.Spectral index and brightness are inferred from measurements made at 1 GHz. Uncertainties in bold are not taken from bibliographic references, but just correspond to a rough uncertainty on the last relevant digit, so they can be underestimated. Age is flagged with a ⋆ for a historical remnant; in this case, the age uncertainty is set from the distance uncertainty. Except for the historical supernovæ, the ages are the observed ages, which differ from the actual ages by d / c.
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.
