Fig. 7


As for Fig. 6, but for the two [O i] fine structure transitions. The blue line shows the estimated level of absorption (negative relative emission) caused by the diffuse gas along the line of sight. It is obtained from the mean of the [C ii] absorption scaled by a factor of 1.6, the ratio of the [O i] 63 μm and [C ii] line opacities for the adopted carbon and oxygen abundances.

This figure is made of several images, please see below:
