Appendix A: Relative disc size changes

Here we present the full numerical results from our parameter study. In contrast to the presentation of the results in the main part of the paper, the values are normalised to the initial disc sizes to allow easier application to arbitrary initial disc sizes. Therefore, r_p is the encounter periastron distance normalised to the initial disc size (r_p = r_peri/r_init) and m₁₂ is the mass of the perturbing star normalised to the mass of the disc-hosting star (m₁₂ = m₂/m₁). The final disc size is obtained by multiplying the initial disc size with the respective value from the table. In the lower-left part of the table, where no values are given, the disc size change is ≲1%, in the upper-right, no values are given, since they may not be reliable (see also discussion in Sect. 2 of the paper).
