Magnification probability P M vs. . The values of and are indicated in each panel. The various symbols correspond to various values of H 0 . To study the variations of P 2 with the other parameters at fixed , we use different symbols to designate the different values of . The large scatter in the values of P 2 is clearly caused by the dependence of P 2 upon .
Several trends are apparent.
We are considering sources with an angular diameter of 1'', hence the smallest possible image separation is of order 0.5''. There is, however, a relationship between the largest angular separations and the value of . Increasing these distances results in higher image separations for a given lensing galaxy. For about one of every 4 models, mostly the ones with , we see a secondary peak at large separation. There are no double images with separations between 4.00'' and 4.75'', but there are several images with separations larger that 4.75''.
