All sources from Gaia DR3 within 500 pc with pEW <  − 0.5 nm but with no XP spectra publicly available. The Gaia scanning law footprint is clearly visible. We colour-code in orange the sources that have no XP spectra because of poor Gaia coverage. The sources in blue do not have XP spectra because of other reasons. Of the sources in orange, we only consider in criterion B (Sect. 2.7) the ones with log(L_{acc,med-GSP-Phot extinction}/L_⊙) > − 3.5.
