Maps of the event rate contrast, RC (see main text). The columns are Jupiter-mass, Neptune-mass, and Earth-mass FFPs from left to right. The rows are ground-based I-band, ground-based K-band, and space-based H-band observations from top to bottom. For the grey monotone maps, the solid (RC =0.03) and dashed (−0.03) contours are drawn. In maps exhibiting very large RC variation these contour levels are seen to be nearly coincident.
