Notes. Column description: 1) observation identifier; 2) observation date; 3) equivalent hydrogen column density as estimated from 21 cm maps (Kalberla et al. 2005); 4) exposure time for MOS1 detector after flare removal; 5) exposure time for MOS2 detector after flare removal; 6) exposure time for pn detector after flare removal; 7) ratio of counts from observation over counts for auxiliary background event files for MOS1 detector. The ratio is computed over the full FOV and in the [7.5−11.85] keV energy band; 8) ratio of counts from observation over counts for auxiliary background event files for the MOS2 detector. The ratio is computed over the full FOV and in the [7.5−11.85] keV energy band; 9) ratio of counts from observation over counts for auxiliary background event files for the pn detector. The ratio is computed over the full FOV and in the [9.2−14.0] keV energy band.
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.
