Table 1

Relative spatial response functions, V_ℓ/V₀, for a number of present and upcoming instruments/missions.

	Intensity			Velocity
	VIRGO	CoRoT	Kepler	HARPS	SONG
	(862 nm)	(660 nm)	(641 nm)^a	(535 nm)	(550 nm)

V₀/V₀	1.00	1.00	1.00	1.00	1.00
V₁/V₀	1.20	1.22	1.22	1.35	1.35
V₂/V₀	0.67	0.70	0.71	1.02	1.01
V₃/V₀	0.10	0.14	0.14	0.48	0.47
V₄/V₀	–0.10	–0.09	–0.08	0.09	0.09

Notes. Notice the increased sensitivity to ℓ = 3,4 modes in velocity. Negative values of V_ℓ mean that the oscillations will appear to have reversed phases.
