CMD for BSSs classified as “upper” and “lower” sequences, based on sequences shown Figure 9, for GC NGC362 and OC Berkeley 39. ZAMS and ZAMS – 0.75 mags are displayed as a purple dashed line and as a green dash-dotted line, respectively. Orange plus (+ symbol) and magenta line represent the MSTO and the best-fitting PARSEC isochrone, respectively (similar to Figure 2). Field/non-member stars are displayed as gray points, whereas confirmed members are displayed as black points. BSSs that lie in the upper-sequence and lower-sequence are symbolized as orange squares and red dots, respectively.
