Caption: Figure 6.

Distribution of hydrogen as a function of galactocentric distance (R/R25). Top subplot: For ionized H II region, the Hα intensity is shown (in logscale in erg s−1 cm−2). Bottom subplot: For neutral gas, the H I column density is shown (in logscale in atoms cm−2). The top and bottom subplots are colored with stellar metallicity ([Z]) and stellar ages (in Myr), respectively.
