cds-question@unistra.frgiant-starsglobular-star-clustersastrometryradial-velocityphotometryspectroscopyvisible-astronomyWe present a study of the internal kinematics of two globular clusters, M10 (NGC 6254) and M71 (NGC 6838), using individual radial velocity (RV) measurements obtained from observations using the Hydra multiobject spectrograph on the WIYN 3.5m telescope. We measured 120 RVs for stars in M10, of which 107 were determined to be cluster members. In M71, we measured 82 RVs and determined 78 of those measurements belonged to cluster members. Using the cluster members, we determine a mean RV of 75.9+/-4.0 (s.d.) km/s and -22.9+/-2.2 (s.d.) km/s for M10 and M71, respectively. We combined the Hydra RV measurements with literature samples and performed a line-of-sight rotational analysis on both clusters. Our analysis has not revealed a statistically significant rotation in either of these clusters with the exception of the inner region (10-117arcsec) of M10 for which we find hints of a marginally significant rotation with amplitude V_rot_=1.14+/-0.18km/s. For M10, we calculate a central velocity dispersion of {sigma}_0_=5.44+/-0.61km/s, which gives a ratio of the amplitude of rotation to the central velocity dispersion V_rot_/{sigma}_0_=0.21+/-0.04. We also explored the rotation of the multiple stellar populations identified in M10 and M71 and found rotation (or lack thereof) in each population consistent with each other and the cluster global rotation signatures.2020MNRAS.494.4548Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/494/4548CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/628/729 : CCD BVIc photometry of M10 stars (Pollard+, 2005)J/A+A/505/117 : Abundances of red giants in 15 globular clustersJ/A+A/505/139 : Abundances of red giants in 17 globular clustersJ/AJ/156/6 : Light element abundances of RGB & AGB stars in M10J/AJ/159/50 : Identifying multiple populations in M71 using CNhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/494/4548https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/494/4548http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/494/4548https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/494/4548https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/494/4548http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/494/4548GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/494/4548/table1 (M10 Hydra Data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/494/4548/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/494/4548/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/494/4548/table1?GETtext/xml+votable180.050000true254.29483-4.078890.005555555555555556Cone search capability for table J/MNRAS/494/4548/table2 (M71 Hydra Data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/494/4548/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/494/4548/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/494/4548/table2?GETtext/xml+votable180.050000true298.4372918.773030.0055555555555555566/12943 310193.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/494/4548?format=asciiOpticaldefaultJ/MNRAS/494/4548/table1M10 Hydra DataB-VB-V color indexmagphot.color;em.opt.B;em.opt.VfloatSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
