Notes. The columns are: (1) field name; (2) observation ID; (3-4) pointing coordinates (J2000); (5) 0.2-2.3 keV vignetted exposure time, averaged in the field and among the 7 TMs; (6) date of the observation starting time; (7) active telescope modules; (8-10) relative astrometric correction on the pointing RA, Dec and the roll angle Θ with 1-σ uncertainties. The mark “s” on the observation ID indicates scanning mode. The ∆RA is already multiplied by cos(Dec), where Dec is the Declination of the field center (Table 1). The ∆RA, ∆Dec in bold font and with a suffix | mark are absolute corrections of each field with respect to WISE counterparts (Sect. 4.3); and the others are relative corrections of each observation (Sect. 2) with respect to the reference observation (flagged as “reference” in the ∆Θ column).
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.
