cds-question@unistra.frseyfert-galaxiesnarrow-band-photometryvisible-astronomyinfrared-astronomyWe report the results from a photometric reverberation mapping campaign carried out with the C18 telescope at the Wise Observatory from 2019 to 2020, targeting the active galactic nucleus MCG 08-11-011. The monitoring was conducted on a daily basis with specially designed narrowband filters, spanning from optical to near-infrared wavelengths (~4000 to 8000{AA}) and avoiding prominent broad emission lines. We aim to measure inter-band continuum time lags, determine the size-wavelength relation, and estimate the host-subtracted AGN luminosity for this system. We use the point-spread function (PSF) photometry to extract the continuum light curves and measure the inter-band time lags using several methods, including the interpolated cross-correlation function, the z-transformed discrete correlation function, a von Neumann estimator, JAVELIN (in spectroscopic and photometric mode), MICA, and a multivariate correlation function. We find wavelength-dependent lags, {tau}({lambda}), up to ~7 days between the multiband light curves of MCG 08-11-011. The observed lags are larger than predictions based on standard thin-disk theory by a factor of ~3-7. We discern a significantly steeper size-wavelength relation than expected for a geometrically thin and optically thick accretion disk, which may result from the contribution of diffuse continuum emission to the flux. These results are similar to those found by previous continuum reverberation mapping campaigns.2023A&A...672A.132Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/672/A132CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/672/A132https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/672/A132http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/672/A132https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/672/A132https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/672/A132http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/672/A132GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/672/A132/table1MCG 08-11-011 normalized NB4250 light curverecnoRecord number assigned by the VizieR team.
