Notes. (1): de Vaucouleurs et al. (1991). (2): Wang et al. (2016). (3): Karachentsev et al. (2007). (4): Walter et al. (2008). We convert to physical units using the distance mentioned in this table. (5): Adopted from Leroy et al. (2019) using the FUV and WISE4 Band. (6): CO luminosity using CO(2-1) from the PHANGS-ALMA survey, Leroy et al. (2021). (7): Kinematic parameters from Heald et al. (2016) that we use in this work and describe in Sect. 2.6.1. We quote here the ones for the central tilted ring. (8): The total H I mass of each region is calculated including single dish observations.
