MCG 08-11-011 narrowband light curves

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.
