VizieR Online Data Catalog: Quintuplet cluster updated stellar census (Clark+, 2018)

This paper reports the results of a combined photometric (HST/NICMOS+WFC3) and spectroscopic study of the Quintuplet cluster, the latter comprising both archival (VLT/SINFONI) and new (VLT/KMOS) data. Photometry is supplied for 108 objects derived from the combined target lists of Figer at al. (1999ApJ...514..202F) and Liermann et al., 2009, Cat. J/A+A/494/1137) and from which stars of late spectral type have been excluded. We present new spectra of 63 unique objects for which our re-reduction of the VLT/SINFONI data has resulted in a much improved S/N, permitting reliable assessment of faint classification diagnostics such as HeII 2.189um and CIV 2.079um. These are supplemented by lower S/N and resolution published data for a further eight stars, yielding a final spectroscopic dataset of 71 stars. Analysis of these data results in the re-classification of ~70% of the cluster members.
