Microlensing maps for a cusp configuration

The maps provided correspond to images which are respectively saddle-point and minimum of the arrival time surface. We also provide simulated images of sources with a disc-like brightness profile or a ring-like brightness profile corresponding to an accretion disc or a torus brightness distribution.

These source profiles should be convolved with microlensing maps of the same spatial resolution to simulate microlensing of the corresponding source and generate probability density function (PDF) of microlensing similar to those shown in Figures 3,4,5,8. These maps can also be used to generate synthetic microlensing lightcurves (Figure 9) or derive PDF for the Rcusp relation (Figure 10).
