Synthetic profiles of the line at λ4934 Å. The synthesis was made with the Turbospectrum code (Gerber et al. 2023) and MARCS models. See details in Sect. 5.2. The atmospheric parameters for the synthesis are similar to those of the star GES J19102677-6003089 (TO-1) in Table 2. The spectrum has resolution R = λ/∆λ = 493 000 and infinite S/N. The solid line (r-process), dashed line (s-process), and blue shade (i-process) profiles are synthesised with the isotopic ratios in Table 5.
