    The detection of gravitational microlensing anomalies
    (1999) Vermaak, Pierre le Roux; Menzies, John; Warner, Brian
    The detection and measurability of microlensing anomalies including planet detection, resolved source, blending and parallax effects are investigated by way of an extensive computer simulation as a function of the observation strategy. The most efficient strategy has a planet detection probability exceeding 753 for the most favourable binary geometry, while results for typical event follow up and survey observations agree well with previous work. A complex dependence of planet detection on the resolved source radius is discovered leading to a possible increase in the probability of detecting planets with mass ratios smaller than q = 10⁻³
