cds-question@unistra.frquasarsvisible-astronomyWide-band photometryphotographic-photometryWe present photographic UBV photometry of the blazar 3C 345 that were made during 79 nights in 1971-1974 and 1983-1984 as a part of the Petersburg Quasar Monitoring Program (PQMP) carried out at the Astronomical Institute of the St.-Petersburg University. These data were previously published by piecemeal (references are presented in Section 4). Now after partial revision these data are united in Table 1 that presents nightly averaged UBV magnitudes together with its rms errors (see Section 4 of the paper for the details). These data were used for the comparison of the spectral indices of the emission in the "fast" (time scales of nearly 10-20 days) and "slow" (time scales of nearly 1 yeas) outbursts in 3C 345.1999PAZh...25..893Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/25/893CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/25/893https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/25/893http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/25/893https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/25/893https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/25/893http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/25/893GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/PAZh/25/893/table1Photographic UBV photometry 3C 345recnoRecord number assigned by the VizieR team.
