J/AJ/133/1041  Velocities and CMT2 photometry in globular M92   (Drukier+, 2007)

The global kinematics of the globular cluster M92. Drukier G.A., Cohn H.N., Lugger P.M., Slavin S.D., Berrington R.C., Murphy B.W. <Astron. J., 133, 1041-1057 (2007)> =2007AJ....133.1041D
ADC_Keywords: Clusters, globular ; Radial velocities ; Photometry, CMT1T2V Keywords: globular clusters: individual (M92, M15) - methods: statistical - stellar dynamics Abstract: We report the determination of high-accuracy radial velocities for 306 members of the globular cluster M92 using the Hydra multiobject spectrograph on the WIYN telescope. We have concentrated on stars outside of the central region of the cluster, located up to 14.4' from the cluster center. Candidate members were selected for spectroscopy based on a photometric metallicity index determined from three-band Washington photometry, also obtained with the WIYN telescope. Description: In 1997 May we observed M92 using the imager on the WIYN telescope. We observed a 40 field mosaic covering a 15' radius centered on the cluster, with a few fields extending out to 20'. We observed each field with the C, M, and T2 filters. File Summary:

Global notes: Note (G1): Where possible, we have used identifications which are generally derived from Table 3 of Tucholke et al. (1996, Cat. J/A+A/312/74), although we have made some additions and corrections where we have deemed them appropriate. These identifiers primarily come from: I-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 1NNN) II-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 2NNN) III-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 3NNN) IV-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 4NNN) V-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 5NNN) VI-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 6NNN) VII-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 7NNN) VIII-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 8NNN) IX-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 9NNN) X-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 10NNN) XI-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 11NNN) XII-NNN = Sandage and Walker (1966ApJ...143..313S, NGC 6341 12NNN) CNN = Cudworth (1976AJ.....81..975C, Cl* NGC 6341 Cud NN) Bu NNN = Buonanno et al.

For stars with configuration 'Z', the velocity is based on the sum of all available spectra.
