The Quintuplet cluster. I. A K-band spectral catalog of stellar sources. Liermann A., Hamann W.-R., Oskinova L.M. <Astron. Astrophys. 494, 1137 (2009)> =2009A&A...494.1137L

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. File Summary:
