All Tables

Table 1: Information about the quasar-galaxy pairs in our sample. $z_{\rm Q}$ is the redshift of the quasar and $z_{\rm G}$ is the redshift of the galaxy. The last two columns list what filters were used in our analysis and the references for the magnitudes.
Table 2: Estimated rest-frame B-V colour for the different quasar images in our sample.
Table 3: Best fits of R_V and E(B-V) together with the 1 $\sigma$ uncertainties. Note that the lowest possible value for R_V here is 0.1, since R_V=0 usually is not defined. Also note that for some redshifts and filter combinations, there is no R_V dependence for the Prévot law. The interval is then given as 0.1-6.0. $z_{\rm d}$ is the redshift of the dust extinction, which is $z_{\rm G}$ for foreground extinction and $z_{\rm Q}$ for host extinction. d is the impact parameter expressed in kpc. When this was unavailable, it is marked with a hyphen in the table. When several laws and/or dust redshifts is either fitted for one image, they are all listed in the table below. The probability for each to obtain a higher $\chi ^2$ value than what was obtained for the fit is given in the last column. We include all fits with a probability larger than 0.5%. The different images are separated by a horizontal line.
Table 4: Additional best fits of R_V and E(B-V) together with the 1 $\sigma$ uncertainties for quasar images which are likely to be dust extincted. The first three quasar images are badly described when using both HST and ground-based images, but are possible to fit with dust when using only the ground-based measurements. The last image is one where the u band magnitude seems to be deviant from the other magnitudes and we have made a fit without it.
