The distribution of ﹩{P}_{{\rm{Direct}}}^{{\rm{Rad}}}/{P}_{{\rm{Ion}}}^{{\rm{Rad}}}﹩ for our target regions split by local galactic environment. The light-blue line shows the median value of 〈τUV〉 (right y-axis) for the regions in each bin. The vertical dashed line indicates where ﹩{P}_{{\rm{Direct}}}^{{\rm{Rad}}}={P}_{{\rm{Ion}}}^{{\rm{Rad}}}﹩. This corresponds to 〈τUV〉 = 0.27.
