Effect of in the T_eff analysis (HD 116852). Models with = 10, 20, and 30 km s⁻¹ are shown respectively in red, green, and blue. The IUE and FEROS data are shown in black. Models with a fuller account of atomic species are shown by dashed lines. The model with = 10 km s⁻¹ and a fuller account of species (dashed red line) is shown with thicker lines in He II λ4542 since it is overlapped with the basic model = 20 km s⁻¹ (solid green). Line S V λ1502 is reproduced by our model with the highest photospheric microturbulence velocity. The emission component of C IV λλ1548,1551 is also betterreproduced with a higher up to 20–30 km s⁻¹. However, T_eff diagnostics are misfitted in this case. It is not possible to fit simultaneously He I λ4471 and He II λ4542 considering = 20–30 km s⁻¹. Our conclusions are unchanged regardless of the improved atomic in the modeling.
