Notes. Median values reported here are calculated considering sources with pEW < − 1.0 nm and using the med-GSP-Phot extinction correction, for direct comparison with Table 4. Median values are only reported for groups where four or more sources could be used for the calculation. The 16th and 84th percentile are in brackets. The full table is available at the CDS and also provides the values calculated with GSP-Phot extinction. References: (C21) Cao et al. (2021; F10) Fedele et al. (2010; H19) Herczeg et al.
