Relevant quotation from abstract: "The main result of this paper is
that it is easy to find low mass halo models consistent with the
observed Galactic rotation curve, which also imply an optical depth to
microlensing similar to that found by the MACHO collaboration. This
means that all-MACHO halos cannot be ruled out on the basis of their
observations... Limits placed on the MACHO content of the Galactic
halo from microlensing surveys in the Magellenic Clouds are
inconsistent and model dependent, and do not provide a secure basis
for rejecting an all-MACHO halo.
