Notes. Results of the photometric analysis of GRB 240419A optical and NIR afterglow, calibrated against the SkyMapper DR4 and 2MASS catalogue, respectively. Magnitudes without the error are upper limits at 3σ c.l. Values are not corrected for the Milky Way extinction along the line of sight, E(B − V) = 0.05 (Schlafly & Finkbeiner 2011).

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.
