Comparison of stellar parameters derived from different wavelength regions. From left to right the differences in T_eff, log g, [M/H], v sin i and ξ are shown. Black, red, and yellow dots are the differences between the parameter value obtained from the 4000–5800 Å spectral range and the parameter value obtained from the wavelength range indicated with the respective colour in the legend of the figure, so p_{4000–5800Å}−p_∆λ. The pink region indicates the internal uncertainty interval from Table 2. The systematic offset (insignificant within the internal uncertainty) in the log g parameter is discussed in detail in Sect. 4.4.
