Comparison of v sin i and vm estimates resulting from the iacob-broad analysis of a subsample of stars v sin i≤ 150 km s-1 and ΘRT≥ 0.5 v sin i. Two different definitions of the macroturbulent profile are considered in the case of GOF results: an isotropic Gaussian profile and a radial-tangential profile. Upper panel: comparison of v sin i values obtained by means of the FT and GOF techniques. Lower panel: comparison of macroturbulent velocities resulting from the GOF analysis. Two options are investigated in the case of the Gaussian profile: (red squares) leaving v sin i as a free parameter as well; (black triangles) fixing v sin i to the value provided by the FT. Dotted lines (both panels) represent the one-to-one relation; dashed black and red lines (bottom panel) correspond to the linear fit to the data represented as black triangles and red squares, respectively.
