Kilonova detection rate as a function of the EM detection limit threshold for our fiducial NSNS (upper panels) and BHNS (lower panels) populations. The blue, green, and red colours indicate the g, z, and J bands, respectively, assuming the ETΔ configuration. In each panel we also report in grey and black the ET2L and ETΔ+2CE configurations. The solid line indicates all the detectable binaries; the dashed and dotted lines show the detectable binaries with ΔΩ_90% < 100 deg² and the ones with ΔΩ_90% < 10 deg², respectively.
