The photometric observations were obtained at the Ege University Observatory, while the spectroscopic ones were carried out at Catania Astrophysical Observatory in the spectral range 5860-6700{AA}. We obtained a high quality radial velocity curve of the system that allowed us to give more accurate values of the orbital parameters.2002A&A...388..298Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/388/298CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/287/817 : Period changes in RT Lac (Keskin+ 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/388/298https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/388/298http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/388/298https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/388/298https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/388/298http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/388/298GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/388/298/table1B and V differential magnitudes of RT Lac in 2000recnoRecord number assigned by the VizieR team.
