Notes. ^(a) Source redshift; ^(b) number of quasar images; ^(c)angular separation between images for double quasars or typical angular size for quadruple quasars; ^(d) r-band magnitudes of quasar images (these values should be interpreted with caution, since we deal with variable objects); ^(e) measured time delay for double quasars or the longest of the measured delays for quadruple quasars (1σ confidence interval); ^(f) classification (redshift). ^(⋆) Time delay in the g-band. There is evidence of chromaticity in the optical delay, since it is 420.6 ± 1.9 d in the r-band. ^(⋆⋆) Redshift from gravitational lensing data and a concordance cosmology. This measurement is in reasonable agreement with the photometric redshift of the secondary lensing galaxy and the most distant overdensity, as well as the redshift of one of the absorption systems.
