Comparison of spectral type differences between TF parameters and MAP values to the MAP veiling values for the Clean samples of Tr14 (blue dots). The samples are divided into two groups depending on the spectral type based on the MAP values. Stars classified as G8 by template fitting are excluded. The blue squares represent the average values calculated within the veiling interval of 0.2. When calculating the average values, we exclude stars whose MAP-based temperature exceeds the maximum template fitting temperature of 5430 K (G8 type). The coloured lines correspond to the curves presented in Fig. 14, which show the change of the spectral type as a function of the veiling tested on the template stars.
