Numbers of detectable binaries in the SMC and LMC.

Object	T_obs (yr)	BH–BH	BH–NS	BH–WD	NS–NS	NS–WD	WD–WD	Total
SMC	4	0.018	0.135	0.571	0.167	1.623	1.069	3.583
SMC	10	0.019	0.189	0.834	0.199	2.182	2.252	5.675
LMC	4	0.026	0.358	1.570	0.395	3.965	4.878	11.192
LMC	10	0.045	0.528	2.014	0.591	5.190	9.384	17.752

Notes. Average numbers of detectable binaries for 4 and 10 years of LISA observations from 1000 simulations of the SMC and LMC. The standard deviation from Poisson uncertainty is 0.032 for all values. Binaries are considered detectable if their S/N > 7.
