Notes. ^(*)Note the A(V) difference between both works, higher than 0.5 mag. Rao et al. (2012) did not find a C/O ratio greater than 1 nor s-process enrichment in HD 107369, as it is expected for an AGB star. In the present study, this star is classified as an unconfirmed post-AGB candidate. ⁽¹⁾Calculated by VOSA, ⁽²⁾Kamath et al. (2022).
