Table 6

The Milky Way mean surface brightness as seen from a vantage point at z = 50 pc and z = 400 pc above the Galactic plane relative to the surface brightness at z = 0.

	Band	b >25°	b < −25°	All-sky
I_{z=50 pc}∕I_z=0
	B_Pioneer	0.76	1.22	1.02

	FUV 1565	0.52	1.42	0.72
	NUV 2365	0.56	1.40	0.74
I_{z=400 pc}∕I_z=0
	B_Pioneer	0.19	1.62	0.93
	R_Pioneer	0.26	1.65	1.28
	FUV 1565	0.002	1.5	0.18
