Notes. Columns: (1) ID number; (2) Source type; (3) Year of discovery; (4) preferred name of the system (GC if located in one); (5-7) Right ascension (RA) and declination (Dec) in equinox J2000, accuracy in the astrometry and source of the coordinates; (8-9) Galactic longitude (l) and latitude (b); (10–11) Estimated distance (d) and height above the Galactic plane (z); (12) References. (a)In Col. 7, the letter preceding the error value indicates the source of the coordinates: radio (r), optical (o), infrared (i), ultraviolet (uv), X-rays (x), Gaia (G), or a combination of them. If RA and Dec errors are different we give both. (b)We use the notation (H) and (He) for distances estimated using thermonuclear bursts, assuming hydrogen-rich and pure helium, respectively. (G) distances from Gaia parallaxes. For systems located in GCs, we report the distance to their host GC (see Sect. 3.1). In the References column (12), ‘y’ refers to discovery year, ‘c’ to coordinates, and ‘d’ to distance.

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.
