J/A+A/445/503       Radial velocities in Omega Cen (NGC5139)     (Reijns+, 2006)

Radial velocities in the globular cluster Omega Centauri. Reijns R.A., Seitzer P., Arnold R., Freeman K.C., Ingerson T., van den Bosch R.C.E., van de Ven G., de Zeeuw P.T. <Astron. Astrophys. 445, 503 (2006)> =2006A&A...445..503R
ADC_Keywords: Clusters, globular ; Radial velocities Keywords: radial velocities - Galaxy: globular clusters: individual: NGC 5139 - Galaxy: kinematics and dynamics Description: List of 1966 radial velocity measurements of stars in globular cluster Omega Centauri (NGC 5139) taken with the ARGUS multi-object spectrometer at the CTIO 4m Blanco telescope. All the stars have a B magnitude brighter than 16.5. The median error is less than 2km/s. The stars are numbered using their LID (Leiden Identification Number) from van Leeuwen et.al. (2000, Cat. J/A+A/360/472). In a companion paper by van de Ven et al. (2006A&A...445..513V), we correct these radial velocities for the perspective rotation caused by the space motion of the cluster. Additionaly 339 stars where measured. These consist of (i) 87 stars with B-V<0.4, (ii) 252 stars not in the van Leeuwen et al. catalog. We suspect that that many of these stars have an erroneous value for their radial velocity. File Summary:
