Updating the microlensing simulator (ML simulator): moving stars in the lensing galaxy

We are updating our current ML simulator at https://microlensing.overfitting.es/ by adding a new ingredient: motions of microlenses. Here below you can find an example. In this example, we consider a point-like source. Additionally, both convergence and shear strength are equal to 0.3, and all mass is due to identical stars (microlenses). The physical size of the magnification map covers 20 Einstein radii with a length side of 2000 pixels. The movie lasts 2 minutes, corresponding to the real time of the simulation in a laptop with i5 processor and 16 GB RAM.
