Notes. All magnitudes in the AB system and uncorrected for the Galactic foreground reddening. Values in brackets correspond to photometric errors in units of valid digits. Upper limits are given at 3σ confidence. Data for the host of GRB 080607 were taken from Chen et al. (2010, 2011), and are not shown in the table.
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.
