Spectra have been taken of member candidates at the Multiple Mirror Telescope (MMT) using Hectospec, Hectochelle, and Binospec, which provide more than 1800 new velocities. Combined with proper-motion measurements of stars in the field by the Gaia-DR2 catalog, we have derived stream membership probabilities, resulting in the detection of more than 200 likely members. These data show the stream extends to more than three times the length shown in the discovery data. A spur to the main stream is also detected. The high-resolution spectra allow us to resolve the stellar velocity dispersion, found to be 1.6{+/-}0.3km/s.2020AJ....159..287Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/287CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/249 : WHAM Northern Sky Survey, V-1.1 (Haffner+, 2003)II/349 : The Pan-STARRS release 1 (PS1) Survey-DR1 (Chambers+, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/AJ/137/94 : Star clusters in M31 (Caldwell+, 2009)J/A+A/530/A31 : Stellar parameters in 10 globular cluster (Lane+, 2011)J/ApJ/736/146 : Radial velocities of stars in Bootes I (Koposov+, 2011)J/AcA/62/357 : Proper motions in 6 globular clusters (Zloczewski+, 2012)J/ApJ/809/59 : Ophiuchus stellar stream with PS1 data (Sesar+, 2015)J/ApJ/816/L4 : Candidate BHB stars in Ophiuchus stream (Sesar+, 2016)J/MNRAS/482/5138 : Galactic GC mean PMs & velocities (Baumgardt+, 2019)J/AJ/158/14 : Stellar pop. globular clusters using APOGEE (Nataf+, 2019)J/AJ/158/223 : RR Lyrae memb. of Pal 5 stellar stream (Price-Whelan+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/159/287https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/159/287http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/159/287https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/159/287https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/159/287http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/159/287GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/159/287/table2 (Spectroscopic observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/159/287/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/159/287/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/159/287/table2?GETtext/xml+votable180.050000true240.97155-7.186190.0055555555555555565/7725 7730 6/30879 30893 30896-30897 30899 30904-30905 30907-30910 30915 30918 30924 30926 30944-30946https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/159/287?format=asciiOpticaldefaultJ/AJ/159/287/table2Spectroscopic observationsSimbadNameSimbad column added by the CDSmeta.idcharnullableD[0/127] Angular distance to stream fiducialpos.angDistancefloatrecnoRecord number assigned by the VizieR team.
