Notes. The redshifts were derived from radial velocities (given in the optical definition) in Pardy et al. (2014) and are thus related to the H I systemic velocities for all LARS galaxies except 12−14 (which have no H I detection). For those, Pardy et al. (2014) report optical Sloan Digital Sky Survey (SDSS) velocities. Stellar masses (log₁₀M_*), Lyα luminosities (L_LyA), and escape fractions () were previously published by Hayes et al. (2014). The metallicities (Z) derived through the empirical O3N2 relation are taken from Östlin et al. (2014), and atomic gas masses (log₁₀M_HI) from Pardy et al. (2014). ^( * )We note that the atomic mass reported for LARS 6 is contaminated by the field spiral UGC10028 and thus is only an upper limit. Typical Lyα scattering distances (D_scatt) for the galaxies were derived by Bridge et al. (2018) and the radii at which the star formation rate density has decreased to 0.01 M_⊙ yr⁻¹ kpc² (R_cutM18), together with axis ratios (b/a_M18) were calculated by Micheva et al. (2018). The blue-band diameters of the 25 mag arcsec² isophote (D_25SDSS) as well as b/a_SDSS were derived from SDSS g-band observations using an SQL query on SDSS DR7. Since the SDSS g-band isophote typically gives sizes that are ∼1.3 times larger than those measured in the Johnson B band (Hakobyan et al. 2012), we divided the g-band diameters by that factor and report estimated values for D_25SDSS here.
