cds-question@unistra.frvisible-astronomyWide-band photometryinfrared-photometryphotometryWe report on the progress of our ongoing photometric monitoring program of spotted late-type stars with automatic photoelectric telescopes (APTs) on Mt. Hopkins in Arizona and on Mt. Etna in Sicily. We present 9250 differential UBV and/or V(RI)c observations for altogether 23 chromospherically active stars, singles and binaries, pre-main-sequence and post-main-sequence, taken between 1991 and 1996. For a description of the UBV and (RI)c photometric system, see e.g. <GCPD/01> and <GCPD/54>1997A&AS..125...11Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/125/11CatalogResearchIsServedByTAP VizieR generic servicerelated-toV/76 : Chromospherically Active Binaries (Strassmeier+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/125/11https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/125/11http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/125/11https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/125/11https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/125/11http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/125/11GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+AS/125/11/cata1Catania APT UBV photometryrecnoRecord number assigned by the VizieR team.
