\tablefoot{$\dagger$ The columns correspond to the following: $num_1$ is the final ID number of the line ratio; $num_2$ is the initial ID number of the line ratio; \textit{stddev} is the final standard deviation for each calibration; \textit{nstars} is the number of stars used for the calibration of each line ratio (out of a total of~451); $\lambda_1$ is the wavelength of the first line of the ratio; $\lambda_2$ is the wavelength of the second line of the ratio; ele$_1$ is the chemical element of the first line of the ratio; ele$_2$ is the element of the second line of the ratio; $c_0$, $c_1$, $c_2$ and $c_3$ are the fitting coefficients for each line-ratio calibration; $T_{\rm eff}^{\rm min}$ and $T_{\rm eff}^{\rm max}$ are the limits in effective temperature of the stars used to calibrate each line ratio; \textit{fit type} is the type of function used for the calibration used: the numbers~1, and~2 correspond to the relation ``$T_{\rm eff}$ vs. $r$'' -- 3, and 4~correspond to the relation ``$T_{\rm eff}$ vs. 1/$r$'' but the spectral lines are inverted in this table for ease of use, and the numbers~5 and~6 correspond to the relations ``$T_{\rm eff}$ vs. log($r$)''. The numbers~2, 4, and 6~correspond to 3rd~order polynomial functions and the numbers~1, 3, 5 correspond to straight line functions. This is easily noticed in the coefficients $c_2$ and $c_3$ (set to zero in straight line fits).}
