Colour-magnitude diagram of hot subluminous star candidates originally selected from Geier et al. (2019), which draws from Gaia DR2. The plot highlights the impact the updated parameters in the Gaia DR2 to Gaia DR3 transition had on the flagship 500 pc sample. The pair-plot shows the shift each star underwent after DR3 where the circle represents the DR3 data. The vertical shift near the MS stems primarily from the improved astrometric solution.
