Sensitivities for SNR = 5 in a one-year integration versus Fourier frequency for equi-arm LISA with armlengths 3 times larger than nominal L = 3 x 16.67 light seconds. The various TDI combinations are indicated as green = α, red = X, black dots = V and blue dashed = E & P. Black dots with poorer senstivity at low frequency = ζ.
