Galactic Bulge microlensing optical depth from EROS-2

Aims.We present a new EROS-2 measurement of the microlensing optical depth toward the Galactic Bulge. Methods.Light curves of $5.6\times 10^{6}$ clump-giant stars distributed over $66\,\rm deg^2$ of the Bulge were monitored during seven Bulge seasons. 120 events were found with apparent amplificatio...
