Caption: Figure 1.

Schematic illustration of our data-driven approach for deriving absolute magnitudes and distances for OB stars, including the identification of stars with emission lines and stars in binary or multiple-star systems. Astrometric parallaxes, spectra, and apparent magnitudes are adopted as inputs.
