Left: Distribution of EEPs for the targets in our sample, 82% of the stars are on the RGB phase while the remaining 18% are core He burning stars. We did not find any MS stars in our sample. Right: HRD for stars in our sample constructed based on the T_eff and L given by SPECIES and colour-coded by the EEPs. Circles represent RGB stars, while squares and triangles are used for primary and secondary RC stars, respectively (see the text for definitions and references). The temperature axis is logarithmic. A theoretical MS constructed with MESA from TAMS to ZAMS is shown as the grey area for comparison. Only a portion of the MS band is shown.
