Notes. Quantities which are results of the modeling (i.e. not explicit model parameters) are displayed in italic and parameters which are fitted to their observed values are displayed into parentheses. Note that flux ratios are used to constrain the lens model only for doubles.
The models of this lensed quasar might be affected by strong systematic errors owing to the large uncertainty on the exact location of the lens from the NICMOS data.
An exponential profile better reproduces the light distribution of the spiral lens galaxy and therefore the ExpD mass model should be prefered to the DV mass model. The Reff used for our DV mass model is the effective radius derived in Table 3 using exponential light distribution.
