We selected target GC candidates using the Washington photometry derived from the deep CCD images taken at the KPNO 4m Telescope. Then we obtained the spectra of 164 target objects in the field of NGC 4636 using the Multi-Object Spectroscopy mode of Faint Object Camera and Spectrograph on the Subaru 8.2m Telescope. We have measured the velocities for 122 objects: 105 GCs in NGC 4636, the nucleus of NGC 4636, 11 foreground stars, two background galaxies, and three probable intracluster GCs in the Virgo Cluster. The GCs in NGC 4636 are located in the projected galactocentric radius within 10' (corresponding to 43kpc). The measured velocities for the GCs range from ~300km/s to ~1600km/s, with a mean value of 932^+25^_-22_km/s, which is in good agreement with the velocity for the nucleus of NGC 4636, 928+/-45km/s.2010ApJ...709..377Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/709/377CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/695/1094 : Chandra observations of NGC 4636 (Posson-Brown+, 2009)J/A+A/459/391 : Dynamics of NGC 4636 globular cluster system (Schuberth+,J/A+A/433/43 : C-T1 phot. of NGC 4636 globular cluster system (Dirsch+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/709/377https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/709/377http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/709/377https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/709/377https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/709/377http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/709/377GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/709/377/table3 (Radial velocities of the objects in the field of NGC 4636)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/709/377/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/709/377/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/709/377/table3?GETtext/xml+votable180.050000true190.60052.76563890.0055555555555555566/26313 263162.9196443747461696e-19 3.2860540898823595e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/709/377?format=asciiOpticaldefaultJ/ApJ/709/377/table3Radial velocities of the objects in the field of NGC 4636recnoRecord number assigned by the VizieR team.
