Abstract (from CDS):
This uncertainty also impinges on one of the most important goals of these surveys, which is to place constraints on the massive compact halo object (MACHO) fraction in M31. Such constraints depend on using Monte Carlo simulations to carry out an efficiency analysis for microlensing detection, and the results should be relatively insensitive to the selection criteria provided the simulations employ the same cuts as the pipelines. Calchi Novati et al. have already derived the constraints associated with their analysis and we present here the constraints associated with the most recent analysis. The constraints are similar if we neglect our long time-scale events and comparable to those found for MACHOs in our own Galaxy by earlier microlensing surveys of the Magellanic Clouds. However, our constraints are different from those of Calchi Novati et al. if we include our long time-scale events.
