Reproduction of Figs 4, 5(a) and (b) on the same axis scale. Target detectability as a function of |$h_{\rm offset}$| and |$i_{\rm offset}$| for |$O_{\rm principal} = (850, 99, 29.8, 28.9)$|⁠. Colour designates relative probability, i.e. number of |$\Omega -\nu$| combinations resulting in a detection for each |$h-i$| pair. Values assume a limiting relative velocity of 10 pix s⁻¹.
