| dc.description | 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 Ho. We present two examples of models predicting Ho=100 km/(s Mpc) (chi^2=4) and Ho=69 km/(s Mpc) (chi^2=24). | |
