The effective GW strain of EMRI events (dots) and the sensitivity curves ﹩\sqrt{{{fS}}_{n}(f)}﹩ of LISA and Tianqin (solid lines). Two mission times for LISA are considered (Wagg et al. 2022a, 2022b). Panels (a) and (b) correspond to cases 1 and 2 in Table 1 when the orbital evolution is considered. The redshift of panel (a) is set to 0.08, and the redshift of panel (b) is set to 0.2.
