Notes. This table is available in its entirety in a machine-readable form at the CDS. A portion is shown here for guidance regarding its form and content.
Positional offset in right ascension and declination relative to the AO guide star Q2 (RA = 17:46:14.690, Dec = − 28:49:40.71 [J2000]).
The combined completeness for each star is the product of its completeness in the Ks-band datasets of both epochs (2003 and 2008) and in the H-band dataset from 2003.
See Appendix B for details of the error determination.
Numbers and spectral identifications from the spectral catalogue by Liermann et al. (2009). Sources in the LHO catalogue which have more than one counterpart in this table are marked with an asterisk.
Cluster membership: cluster members are indicated by “y”, field stars according to their measured proper motions are indicated by “n”. Proper motion members rejected based on their spectral type (M, K supergiants) or their colour are marked with “n st” or “n cc”, respectively.
Initial masses as determined from the 3, 4, 5 Myr Padova isochrones (with PMS part derived from Pisa-FRANEC PMS stellar models, see Gennaro et al. 2011) and the 4 Myr Geneva isochrone. All isochrones assume solar metallicity. For Wolf-Rayet stars the stated mass ranges are inferred from the underlying stellar models of the respective isochrone.
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.
