Notes. Star formation rates and stellar masses from Leroy et al. (2021) for all galaxies except NGC 5055, which is from Leroy et al. (2019). Feather spacing (λ_fil) from 1 – Meidt et al. (2023); 2 – La Vigne et al. (2006) tabulated in Mandowara et al. (2022); circular velocities (v_c) from Lang et al. (2020) for all except NGC 5055 and IC 5332, which are from McGaugh & Schombert (2015) and Meidt et al. (2018), respectively.
