YS coefficient and YS-induced orbital drift rate for confirmed small binary asteroids, assuming thermal inertia of 100 tiu (left) and 500 tiu (right). The colours indicate the heliocentric semi-major axis, with bluer colours representing greater distances from the Sun. The size of each circle corresponds to the size of the primary asteroid. As thermal inertia increases, blue dots tend to move downwards and red dots upwards, although the outcome is a complex function of thermal inertia.
