We have carried out line observations to map the kinematics of an evolved, actively star forming filament G82.65-2.00. The filament was first identified from the Planck data as a region of particularly cold dust emission and was mapped at 100-500m as a part of the Herschel key program Galactic Cold Cores. The Herschel observations cover the central part of the filament, corresponding to a filament length of ~12pc at the assumed distance of 620pc. CO observations show that the filament has an intriguing velocity field with several velocity components around the filament. In this paper, we study the velocity structure in detail, to quantify possible mass accretion rate onto the filament, and study the masses of the cold cores located in the filament. We have carried out line observations of several molecules, including CO isotopologues, HCO^+^, HCN, and CS with the Osaka 1.85m telescope and the Nobeyama 45m telescope. The spectral line data are used to derive velocity and column density information.2017A&A...608A..21Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/608/A21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/608/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/608/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/608/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/608/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/608/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/608/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/608/A21/list (List of datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/608/A21/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/608/A21/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/608/A21/list?GETtext/xml+votable180.050000true313.533441.565970.0055555555555555566/14676 14678https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/608/A21?format=asciiRadiodefaultJ/A+A/608/A21/listList of datacubesTitleTitle of the FITS file (1)meta.title;meta.fitsrecnoRecord number assigned by the VizieR team.
