BTFR for the sample of galaxies with redshift-independent distances from SPARC (gray+blue points; Lelli et al. 2016, 2019) supplemented with galaxies from Ponomareva et al. (2016, 2018, red points). The dashed line indicates the relation fitted for V_flat, with the shaded gray area representing the observed vertical scatter. The stars indicate ESO 358-60 on the relation for the best-fit model (red) and at a distance of 20 ± 1 Mpc (blue). The red box is determined by its top-right corner, where ESO 358-60 is positioned on the relation when using the upper limit derived from the rising RC model.
