Figure 1: aLIGO (left) and AdV (right) target strain sensitivity as a function of frequency. The
binary neutron-star (BNS) range, the average distance to which these signals could be detected, is
given in megaparsec. Current notions of the progression of sensitivity are given for early, mid and late
commissioning phases, as well as the final design sensitivity target and the BNS-optimized sensitivity.
While both dates and sensitivity curves are subject to change, the overall progression represents our
best current estimates.
