Notes. Errors are quoted at a 90% confidence level. The first epochs in each source correspond to the high-quality datasets that were jointly fitted and from which we determine Γ and nH. The rest of the data were fitted individually by freezing nH and/or Γ to the best-fit value found in the joint fit of the high-quality data. The full table is available at the CDS.
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.
