Notes. From left to right, the first four columns give the wavelength of the line pairs adopted for the LDR, while Col. 5 gives the range in effective temperature in which the individual LDRs were calibrated. Columns 6–11 list the coefficients of the analytical relation adopted for the calibration, while Col. 12 gives the analytical formula. The last column gives the reference for the calibration of the LDR. The complete table is available at the CDS.
