Example of convergence for the alternative model (see Table 2). All datasets (RV, TTV, VIS, CLO, T3, SYN, SED, SKY2) were taken into account, with alternative weights w_rv = 100, w_ttv = 1000, w_vis = 0.1, w_clo = 0.1, w_syn = 0.1, w_sky2 = 1000.0. Two of the stellar components (Ac2, Aa2) were forced to be on the main sequence, which results in tension (an increase in several χ² contributions after 800 iteration). The nominal model does not exhibit such tension.
