Abstract
We apply elliptical isothermal mass models to reproduce the point source properties, i.e. image positions, flux density ratios and time delay ratios, of the quadruple lens B1608+656. A wide set of suitable solutions is found, showing that models that only fit the properties of point sources are under-constrained and can lead to a large uncertainty in the prediction of H_◦. We present two examples of models predicting H_◦ = 100kms^(−1)Mpc^(−1) (χ^2 = 4) and H_◦ = 69kms^(−1)Mpc^(−1) (χ^2=24).
