Donor star mass loss rate for each of the best models with solar composition: E_100_01 and E_100_03. As the only variation between these models is on the β value, and this parameter does not affect strongly the mass loss episode, their plots are mostly overlapping. The black dashed horizontal lines represent the estimation for the mass loss rate for V404 Cyg of Ṁ_d = 1.1 × 10⁻⁹ M_⊙ yr⁻¹ is denoted with a dashed horizontal line. As for the dashed vertical lines, they represent the times of the minimum value of the epsilon squared function.
