Galactic distribution of HdC and DYPer type stars (large dots) and EHe stars (triangles) colour-coded by their mean geometric distances in kilo-parsec as determined by Bailer-Jones et al. (2021). The coloured symbols are for targets with a valid astrometric fit and a parallax S/N higher than 3. All other stars are indicated in grey. Four bright RCB stars, R CrB, V854 Cen, V CrA and SU Tau are indicated with crosses that are coloured according to the distance estimated with an absolute magnitude M_V ~ −5 mag (see text). Names are shown for the stars located outside the Galactic bulge area. Bottom left: zoom on the Galactic centre area, |1| <30^º and |b| <15^º.
