Fig. 2


Temporal density distribution of the ≈51 billion G–band observations contributingto Gaia DR2. Each column in the heatmap shows the density of observations within a given OBMT day for each OBMTday. The OBMT revolution is shown on the top abscissa axis to facilitate interpretation. The high-density features are the Galactic plane crossing the two FoVs either in the Galaxy inner or outer direction (see the text for more details). The gaps related to the events listed in Table 1 are also visible. Other small gaps are due to telemetry data that could not be included in Gaia DR2 because they were affected by processing problems.

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.
