Comparison of the spectral templates best fit SpT (Sect. 3.1.2) with the SpT coming from spectral indices (Sect. 3.3). The objects are color-coded based on the final membership discussed in Sect. 3.1.4: members (orange circles), possible members (blue squares) and nonmembers (black crosses). The solid line represents the 1:1 SpT relationship, and the dashed lines represent a ±1 SpT deviation from the 1:1 relationship.
