MOA-2011-BLG-293Lb: A Test of Pure Survey Microlensing Planet Detections.

Because of the development of large-format, wide-field cameras, microlensing surveys will span the full range of significance levels including planetary signals too small to be distinguished from the noise. At present, we do not understand where the threshold is for detecting planets. MOA-2011-BLG-293Lb is the first planet to be published from the new surveys.This event suggests a means to probe the detection threshold, by analyzing a large sample of events like MOA-2011-BLG-293.
