As a further test, we derive the gravitational lens properties of our model, in particular, the demarcation curves between ‘weak’ and ‘strong’ lensing. Accordingly, strong lensing with typically three images is almost three times more probable for our solitonic model than for the Burkert fit. Moreover, some prospective consequences of a possible flattening of DM haloes are indicated.
