Marginalised posterior PDFs of the orbital parameters of TOI-402.01 (subscript 1) and TOI-402.02 (subscript 2). The planetary mass posterior PDFs have been derived by considering the orbital inclinations of TOI-402.01 and TOI-402.02 with their respective errors (see Table 2), and the stellar mass with its respective error (see Table 1). The red vertical lines represent the mean value of each distribution. The title of each subplot gives this mean value for each marginalised posterior PDF, in addition to the rms of the distribution giving therefore the 68% confidence interval error.
