Detection probability of a companion to Rheinland and Kurpfalz on their heliocentric orbit: (i) the blue curve is p₁ during the phase 1 of CSS operations, and (ii) the red curve is p₂ during the phase 2 of CSS operations. The black curve is the combined probability p during both phases (Eq. (1)). The gray area allows the existence of an additional small body in the system, whose maximum probability of occurrence is complementary value to the probability p on the left ordinate.
