Notes. Data are from Walter et al. (2008) and Leroy et al. (2008) unless otherwise noted. Columns: (1) galaxy name; (2) inclination angle; (3) optical diameter measured at the 25 mag arcsec−2 isophote in B-band; (4) distance; (5) absolute B-band magnitude; (6) galaxy morphological classification; (7) optical classification of the nuclear spectrum, from Ho et al. (1997) where Sy = Seyfert and T = transition object between HII nuclei and LINERs; (8) SFR based on the hybrid FUV+24 μm conversion that has an uncertainty of 0.3 dex; (9) radius of the actively star forming disc (within the last ≈100 Myr), estimated from the radial extent of the RC emission; (10) SFR surface density is with an uncertainty of 0.3 dex; (11) total mass , where r25 is the radius of the galaxy estimated from d25 using the distance D, and v100 is the rotation speed in units of 100 km s−1, with an uncertainty of 0.1 dex; (12) maximum rotation speeds in the flat part of the rotation curve with typical uncertainties of ±3 km s−1.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
