Ba, Mg, and Mn NLTE abundance corrections as a function of the evolutionary stage and surface gravity for all models listed in Table 2. For Mn, the lines are grouped in multiplets and the average NLTE correction is shown. The LTE reference is chosen to be a common measured abundance in GCs, that is [Ba/Fe]= −0.2, [Mn/Fe] = −0.4, [Mg/Fe] = +0.4. The empty markers represent the horizontal branch stars.
