A total of 635 plates imaging the program stars have been found and the brightness estimated using the Henden & Munari (2000A&AS..143..343H) UBV(RI) photometric sequences. These historical data have allowed for the first time the determination of the orbital periods of Hen 2-468 (774 days) and QW Sge (390.5 days), a significant improvement in the orbital period of LT Del (465.6 days) and for V407 Cyg an evaluation of the Mira's pulsation period and complex lightcurve shape in the red (R and I bands). Some previously unknown outbursts have been discovered too.2002A&A...386..237Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/386/237CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/370/503 : BV(RI)c photometry of 7 symbiotic stars (Munari+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/386/237https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/386/237http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/386/237https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/386/237https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/386/237http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/386/237GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/386/237/stars (List of the 8 stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/386/237/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/386/237/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/386/237/stars?GETtext/xml+votable180.050000true280.10069167-8.732702780.0055555555555555566/10183 12912 12964 13288 14374 15372 29527 30374https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/386/237?format=asciiOpticalInfrareddefaultJ/A+A/386/237/starsList of the 8 starsrecnoRecord number assigned by the VizieR team.
