Abstract:
Three very massive clusters are known to reside in the Galactic center
region, the Arches cluster, the Quintuplet cluster, and the central
parsec cluster, each of them rich in young hot stars. With new
infrared instruments, this region is no longer obscured for the
observer. For understanding these very massive clusters, it is
essential to know their stellar inventory. We provide comprehensive
spectroscopic data for the stellar population of the Quintuplet
cluster that will form the basis of subsequent spectral analyses.
Spectroscopic observations of the Quintuplet cluster were obtained
with the Integral Field Spectrograph SINFONI-SPIFFI at the ESO-VLT,
with the ESO VLT UT4 (Yepun) telescope between May and July 2006.
The inner part of the Quintuplet cluster covered by 22 slightly
overlapping fields, each of them of 8"x8" in size. The spectral range
comprises the near-IR K-band from 1.94 to 2.45um. The 3D data cubes of
the individual fields were flux-calibrated and combined to one
contiguous cube, from which the spectra of all detectable point
sources were extracted.
Description:
We provide Table 2 from the paper "The Quintuplet cluster I. A K-band
spectral catalog of stellar sources" in ascii format, to serve as a
look-up table for the detected stellar sources in the central cluster
region. Stellar spectra to the sources will be available in July 2009.
The sample comprises 98 early-type stars and 62 late-type stars with
assigned spectral types and derive synthetic K-band magnitudes.
Additionally we list determined radial velocities and alias names for
the sources.
Catalog in ascii mode will be available at the CDS in July 2009.
