Microturbulence as function of T_eff for the stars in Table 1. Panels descriptions, from left to right, are as follows. Quantities derived from the subordinate lines at λ5853, 6141, and 6496 Å, respectively. TO stars are excluded on purpose. Vertical bars represent υ_mic ranges computed by the intersections of the trends with the shades in Fig. 5. Orange dashes are medians of contiguous bars, which correspond to stars in the stages indicated on the top; these values are defined as $v_{mic}^{Ba}$. Brown dashes represent $v_{mic}^{Ba}$ if it were derived using A(Ba) of the TO-2 star (red dashed line in Fig. 5). Blue dashes, gray dashes, and circles represent $v_{mic}^{LTE}$, $v_{mic}^{NLTE}$, and $v_{mic}^{fit}$, respectively. Blue bars are the errors of $v_{mic}^{LTE}$. Green dashes are computed with the relation based on 3D models of Dutra-Ferreira et al. (2016).
