In the astrometric reduction, three earlier epoch plates taken at Sheshan, Shanghai, China, in 1958 and four recent epoch B-passband CCD frames taken at Kavalur, India, were used. The data were reduced to a catalogue based on measurements of stars on seven plates with an epoch period from 1917 to 1979 taken in Bonn, Germany, and ultimately to the Hipparcos catalogue. The reduction was done with the central overlapping method. Based on the new proper motion data, the membership probabilities of 115 stars were determined. Furthermore, three colour-magnitude diagrams (CMD) of V versus B-V, V-R and V-I, respectively, for HB and GB stars were constructed from CCD photometry obtained with the Vainu Bappu Telescope. An absolute proper motion of the cluster of -2.08+/-0.48mas/yr in right ascension and -3.07+/-0.46mas/yr in declination has been obtained. The space velocity and apogalactic distance of the cluster with respect to the Galactic standard of rest were calculated. In contrast to the first results given in the literature we obtain a significantly lower velocity and a smaller apogalactic distance for NGC 4147.2000A&AS..142..373Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/142/373CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/142/373https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/142/373http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/142/373https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/142/373https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/142/373http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/142/373GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/142/373/table9 (Absolute proper motions and BVRI photometry of 115 stars in the region of globular cluster NGC 4147)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/142/373/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/142/373/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/142/373/table9?GETtext/xml+votable180.050000true182.493647583318.56913083330.0055555555555555566/28067https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/142/373?format=asciiOpticalInfrareddefaultJ/A+AS/142/373/table9Absolute proper motions and BVRI photometry of 115 stars in the region of globular cluster NGC 4147recnoRecord number assigned by the VizieR team.
