Table C.3:

Line widths in the linear phase for a perturbation corresponding to the Odin beam at a number of redshifts.
Redshift	Temp	Size^a	Mass^a	Fract. width	Line width^b	Width at 500 GHz
z	T	L	M	$\Delta \nu / \nu$	$\Delta \upsilon_{\rm Linear}$	$\Delta \nu$
	[K]	[kpc]	[ $M_\odot$ ]		[km s^-1]	[GHz] ]
10	30	540	4 $\times$ 10¹²	2 $\times$ 10^-3	720	1.3
20	57	320	6 $\times$ 10¹²	4 $\times$ 10^-3	1100	2.1
50	139	150	9 $\times$ 10¹²	7 $\times$ 10^-3	2000	3.7
