Sensitivities for armlengths 3 x smaller than nominal

Sensitiviy of LISA (SNR = 5 in one year integration) to sinusoidal signals, for various Time-Delay-Interferometry laser-noise cancelling data combinations. Arm lengths are assumed to be 3x smaller than nominal but spacecraft performance (laser power, optics size) is as for nominal LISA. The various laser-noise-cancelling TDI combinations are shown: green = &alpha, red = X, black dots = V, blue dashed = E and P, black dots with poorer sensitivity at low frequencies = ζ.
