cds-question@unistra.frinfrared-photometryvisible-astronomyWide-band photometryearly-type-starsTablea1 contains photoelectric VRI Cousins photometry for 63 Am stars observed on the 17th June, 1996 with the 1.52m telescope of the Observatorio Astronomico Nacional (O.A.N.) at Calar Alto (Almeria, Spain), and on the 25th and 26th of the same month using the 1m Jakobus Kapteyn telescope at the Observatorio del Roque de los Muchachos (O.R.M., Canary Islands, Spain). The reduction procedure followed is explained in Rossello et al. (1985A&AS...59..399R) and Landolt (1983, Cat. <II/118>; 1983AJ.....88..853L) standard stars were used. We provide the V magnitude, the (V-R) and (V-I) colour indices, their associated standard errors and the number of observations performed for each star.1999A&A...343..446Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/343/446CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/343/446https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/343/446http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/343/446https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/343/446https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/343/446http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/343/446GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/343/446/tablea1V, (V-R) and (V-I) of 63 Am starsrecnoRecord number assigned by the VizieR team.
