cds-question@unistra.frquasarsinfrared-photometryvisible-astronomyWide-band photometryccd-photometryThe observations presented in table 3 were made by using the 1.03m Dall-Kirkham-type telescope (f/8.45) of Tuorla Observatory with a SBIG ST-8 CCD-camera and a standard V-band filter. Table 4 includes data (B-, V- , and R-bands) observed at the Nordic Optical Telescope (NOT) on La Palma. Corrections for dark-current effects, additive effects (bias) and multiplicative effects (flatfield) were applied. Due to the relatively small field of view of the telescope separate frames of comparison stars were exposed for Mrk 421 and 4C 29.45. For the other objects normal differential photometry methods were applied. Exposure times with the Tuorla 1.03 meter telescope were between 60 and 240 seconds for objects brighter than 16 mag. For fainter objects, we have combined several exposures to achieve a sufficiently high signal to noise ratio.2000A&AS..143..357Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/143/357CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/143/357https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/143/357http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/143/357https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/143/357https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/143/357http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/143/357GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/143/357/table1 (Objects in Tuorla quasar monitoring campaign)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/143/357/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/143/357/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/143/357/table1?GETtext/xml+votable180.050000true18.02416722.7441670.0055555555555555566/579 2414 4695 4770 5423 7570 7896 8915 9460 9633 9711 13496 13927 16059 19271 19398 19831 20099 21935 22363 23127 26131 26293 28454 28479 28492 28517https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/143/357?format=asciiOpticalInfrareddefaultJ/A+AS/143/357/table2Tuorla 1.03 m telescope V-band dataNameName of the ObjectcharprimaryrecnoRecord number assigned by the VizieR team.
