Notes. BL,   LD,   CGP,  SS, and GD refer to the blending, limb-darkening, close-in giant planet companion, stellar spot, and gravity-darkening effects, respectively. and are the average values of maximum chromatic deviations in detectable (simulated) microlensing events. Also, f100, f200 and f500 represent the fraction of the simulated events with detectable chromatic perturbations, and with the maximum magnification factor higher than 100, 200, and 500, respectively. The last column (No.) reports the number of simulated events with detectable perturbations.
