    Image shows magnification pattern, obtained with backward ray shooting method. Click the image to enlarge and see it in high resolution. Binary lens parameters: mass ratio q = 0.2, separation R0 = 1 RE. Small circles marks lensing stars with sizes corresponding to their masses. Line shows the path of relative source-lens motion with parameters: theta= 30 deg, impact param. b= 0.065 RE. Light curve of this event is shown below.

    Source position is marked by circles on above image. Different circles correspond to different source radiuses. On image below see how would look image of this source if lensed by lens like showed above. Small circles on both images are positions of lensing masses.
