J/A+A/448/155     Radial velocities of Leo I globular clusters  (Bergond+, 2006)

Wide-field kinematics of globular clusters in the Leo I group. Bergond G., Zepf S.E., Romanowsky A.J., Sharples R.M., Rhode K.L. <Astron. Astrophys., 448, 155-164 (2006)> =2006A&A...448..155B
ADC_Keywords: Galaxies, nearby ; Clusters, globular ; Velocity dispersion ; Radial velocities ; Spectroscopy Keywords: galaxies: elliptical and lenticular, cD - galaxies: halos - galaxies: kinematics and dynamics - galaxies: star clusters Abstract: VLT/FLAMES radial velocities for 50 Globular Clusters (GCs), 37 field stars and 21 unclassified objects around the Leo I group galaxies NGC 3379 and NGC 3384 are presented. Object Id and BVR photometry are from Rhode & Zepf (2004AJ....127..302R). Positions (J2000.0) should be accurate to ∼0"2 or better w.r.t. the GSC2.1 catalogue. Heliocentric radial velocities and their errors were estimated by fitting the peak (see the width, heigh, and Tonry & Davies (1979AJ.....84.1511T) coefficient) of the cross-correlation function (CCF) with the IRAF/RV package task FXCOR, using simulatenous and ELODIE library stellar templates. Objects have been assigned three quality class, class A being the most secure velocity determination, and class C the least secure; the latter objects require confirmation, and such GCs were not considered for the dynamical analysis presented in the paper. Description: The FLAMES observations were carried out in service mode on VLT/UT2 (Kueyen), with the GIRAFFE/MEDUSA configuration. Our observing programme consisted of five 2595-s exposures taken on separate nights, in May-June 2003, under good seeing (∼0.7") conditions. File Summary:
