Simulate the microlensing light curves due to crossing of a point-like and
an extended circular source over the magnification map (given as FITS file
"mlmap.fits.gz") for a "typical" lens (z_d = 0.5, z_s = 2). Assume that both
sources cross the map with effective velocity v_eff = 5 R_E / yr along its
diagonal path between (1 R_E, 1 R_E) and (15 R_E, 15 R_E), and that circular
source has radius R_s = 0.8 R_E and Gaussian distribution of brightness
with standard deviation: a) sigma = 0.4 R_E and b) sigma = 0.1 R_E.
Use the provided Python scripts to perform the required simulations, and
then discuss the resulting simulated microlensing light curves.
