Notes. Column (1) galaxy name; (2) position angle of the major axis, B08 and O15 refer to the receding major axis, ( * ) indicates uncertain value; (3) rms noise of the 6-arcsec map; (4) semi-major and semi-minor axes of the integration ellipse for the 6-arcsec map; (5) integrated flux density from the 6-arcsec map; (6) rms noise of the 20-arcsec map; (7) semi-major and semi-minor axes of the integration ellipse for the 20-arcsec map; (8) integrated flux density from the 20-arcsec map; (9) alternative star formation rate from Hα [H18], hybrid Hα and 24 μm [C10, K11, NGC 855, NGC 5033], and 24 μm [W15, NGC 5195].
