Comparison for the exoplanet microlensing event distribution in the Galactic co-ordinates (top), the lens-source distance relation (middle), and the lens distance-mass relation (bottom). The coloured markers are the events outside the bulge, as is labelled in each panel, and the dark dots are the exoplanet microlensing events towards the bulge. Data was taken from the NASA Exoplanet Archive. Note that the scale on the top panel is very different between the longitude (l) and latitude (b) axes.
