Scatter plots indicating the impact of the resolution on the number of superbubbles found per galaxy. Top: number of superbubbles detected per galaxy normalised by the galaxy’s molecular mass as a function of distance. The marker shape indicates galaxy type (see legend). The colour of the markers shows the number of bubbles detected. Bottom: mean bubble radius (crosses) per galaxy. The black dots above and below the mean radius shows the individual radii found per galaxy. The colour of the markers shows the physical resolution of the CO data.
