Table 1:

Comparison of the observed ratios of H₂ lines to H₂(1-0) S1 at 2.12 $\mu {\rm m}$ in four different regions of both galaxies (see text) with fluorescent and thermal excitation models by Black & van Dishoeck (1987).
He 2-10
Line	$\lambda$ ( $\mu {\rm m}$ )	East	Center	Edge	West	thermal	fluoresc.
2-1 S(3)	2.073	0.22	0.21	0.18	0.28	0.08	0.35
2-1 S(2)	2.154	0.08	0.09	0.07	0.12	0.04	0.28
2-1 S(1)	2.248	0.31	0.18	0.35	0.27	0.08	0.56
NGC5253
Line	$\lambda$ ( $\mu {\rm m}$ )	Cluster 5	Cluster 5a	SW	W	thermal	fluoresc.
2-1 S(3)	2.073	0.27	0.34	0.27	0.25	0.08	0.35
2-1 S(2)	2.154	0.22	<0.13	0.22	<0.09	0.04	0.28
2-1 S(1)	2.248	0.37	0.36	0.43	0.34	0.08	0.56

Notes. The uncertainties in the ratio are on the order of 30% in He 2-10 and 15% in NGC 5253.
