Image Details
Caption: Figure 9.
An atlas of gas, stars, and star formation is the same as Figure 1 but for M33. For Hα, we show the unfilled version (i.e., NaNs were not assigned the average of all valid pixels in the same deprojected, galactocentric radial bin) for visualization purposes to show how many artifacts we have masked.
