Graphical output from the iacob-broad semi-automatized tool to determine projected rotational velocity (3 sin i) and non-rotational broadening. The example shown is for the star PGMW 3053, using the metal line of N III λ4515 in absorption. Five panels are displayed: (upper left) the line profile of the line; (upper right) the Fourier transform (FT) of the line; (lower right) 2D χ-distributions resulting from the Goodness-of-fit (GOF) analysis, and their projections (middle and lower left). The fitting in red indicates the v sin i corresponding to the first zero of the FT; the blue indicates the result for v sin i and “macroturbulent” velocity (v_mac) from GOF; green indicates the result for v sin i from the GOF, if v_mac is assumed to be zero; and purple shows the v_mac from the GOF assuming v sin i is the first zero of the FT. The equivalent width (EW) and S/N measured in the neighboring continuum of the line are also indicated. In this case, EW = 50 mÅ and S/N = 196. Here, we take the v sin i value determined with the FT, and the v_mac from the GOF, the fitting of which is shown in purple. Thus, for this star, we report v sin i = 88 ± 4 km s⁻¹, and v_mac = 15 ± 4 km s^–1.
