Detection efficiency: Solid (dashed) lines show efficiencies, taking (or not) into account blending effects. The gray lines show efficiencies of the analysis adding the constraint tE > 200 days. The gray histograms (not normalized) are the expected tE distributions for a halo made of 10, 100, and 1000 M⊙ compact objects (from left to right).
