log(N_H) vs. v_out (left) and log(ξ) vs. v_out (right) for the WA, UFO_L, and UFO_H components of IRASF11119 (red diamonds). The known soft-band detected fast winds from the literature are shown with colored points: light green (Gupta et al. 2013b); cyan (Gupta et al. 2015); sky blue (Longinotti et al. 2015); magenta (Reeves et al. 2016); blue (Pounds et al. 2016); orange (Jiang et al. 2018); yellow (Serafinelli et al. 2019); dark green (Krongold et al. 2021). The low-velocity WAs region (green), UFOs region (cyan), and the correlation fits linking low-velocity WAs and UFOs (dashed black lines) are derived from Tombesi et al. (2013).
