L_bol estimated from each model grid and for each spectral range using the Stefan–Boltzmann law, based on the estimated T_eff (see Figure 8) and radius (see Figure 9). Objects with a negative color anomaly are represented by small light dots, while those with a positive color anomaly are shown as large deep dots. The L_bol values derived from the reconstructed SED (see Section 3.3) are indicated by red crosses.
