Histograms of three observational properties of galaxies in and around A2626. (a) Distribution of the peak signal-to-noise ratio in the H I maps. (b) Number of beams enclosed by the 3σ contours of the H I maps. (c) Distribution of 3σ column density levels in the H I maps. The 3σ H I column density used here is the average column density from the signal-to-noise ratio map where the pixels with 2.5 < (S/N) < 3.5 were selected following Healy et al. (2021a).
