Notes.Data for bars contains the visual estimated barlength (a), the maximum ellipticity in the bar region (ϵ), the visual estimated position angle (PA), and the barlength obtained from the ellipticity maximum (a(ϵ)). They are given in both the sky plane and the disk plane, the conversion is made using P4 orientation parameters (Salo et al. 2015; Table 1). For bars the disk plane values are given only when a reliable ellipticity maximum was found and the galaxy inclination i< 65°. For other features the parameters are obtained from fitting ellipses to points tracing the structure. A quality flag for our measurement is also given: 1 indicates a good fit and unambiguously identified feature; 2 indicates a hard to trace feature; 3 indicates an uncertain feature identification (due to high inclination of host galaxy or incomplete feature).
