Notes. Columns are: (1) – Galaxy name. Columns (2)–(4) and (6)–(8) – Number of GC-LMXBs (NGC−X) and field LMXBs (NF−X) in different luminosity ranges (1, 2 and 3 refer to log (LX) ranges of 35–36, 36–37 and >37) with incompleteness higher than 0.5. The source numbers are not corrected for incompleteness, and the CXB contribution is not subtracted. Columns (5) and (9) – The specific number of GC-LMXB (per GC) and field LMXBs (per 1010 M⊙) in the highest luminosity bin log (LX) > 37. The numbers are corrected for incompleteness of X-ray source lists, the contribution of CXB is subtracted. Note that the specific numbers of GC-LMXB are not corrected for incompleteness of the GC lists and are given here as a characterization of our sample, rather than of the properties of GC systems in different galaxies.)
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.
