cds-question@unistra.frbl-lacertae-objectsccd-photometryWe first introduce a novel photometric system that consists of a Schmidt telescope, an objective prism, a CCD camera, and, in particular, a multipeak interference filter. The multipeak interference filter enables light in multiple passbands to pass through it simultaneously. The light in different passbands is differentially refracted by the objective prism and is focused on the CCD in separate regions, so we have multiple "images" for each object on the CCD frames. This system enables us to monitor blazars exactly simultaneously in multiple wave bands on a single telescope and to accurately trace the color change during the variation. We used this novel system to monitor the BL Lacertae object S5 0716+714 during 2006 January and February and achieved a very high temporal resolution. The object was very bright and very active during this period. Two strong flares were observed, with variation amplitudes of about 0.8 and 0.6mag in the V' band, respectively.2007AJ....133.1599Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/1599CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/327/61 : BV(RI)c photometry of S5 0716+714 (Ghisellini+ 1997)J/A+A/402/151 : S5 0716+714 UBVRI photometry (Raiteri+, 2003)J/AJ/129/1818 : Photometry of S5 0716+714 (Wu+, 2005)J/A+A/451/435 : BV(RI)c photometry of S5 0716+714 (Montagni+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/1599https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/1599http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/1599https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/1599https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/1599http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/1599GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/133/1599/table2Observational log and results in the B', V' and R' bandse_V'magError in V'magmagstat.error;phot.magfloatrecnoRecord number assigned by the VizieR team.
