Known ground-based orbital solution for the binary star HD 223323 (Gaia DR3 2852594583674129152). The primary orbit is illustrated with a black continuous line and the secondary with a magenta dashed line. The SB 1 RV measurements are indicated by red dots, whereas the SB2 ones are marked in blue (for the primary) and in cyan (for the secondary). The expected, typical RV of the blend is plotted in green (see text for explanations).
