Ratios of the galaxy’s UV, [C II]158 μm, [O III]88 μm, and dust continuum emission. The images are convolved to the smallest common beam: the [O III] beam where those data are involved and the [C II] beam otherwise. Parts of the ratio maps with S/N below 3 in the denominator are masked white, with increasing transparency from 3 to 6. The color range is normalized across the S/N > 6 part of the map for the panels involving the HST data. Contours for the [C II] and [O III] line emission and the UV emission are shown as dotted black, dashed green, and solid violet lines.
