Caption: Figure 23.

PHANGS–ALMA baseline lengths. Illustration of uv baseline lengths in the 12 m (blue, upper) and 7 m (red, lower) arrays. Each line shows one observation, with the circle showing the median value and the lines showing the full minimum to maximum baseline length in the data. A green shaded region indicates the 12 m diameter of the total power antennas. For a more detailed look at the distribution of collecting area vs. baseline length in one case, see Figure 25.
