Residuals from the comparison between the stellar atmospheric parameters for the stars in the IRTF spectral library and those compiled by Cesetti et al. (2013; present work – Cesetti). The circles represent the values for the IRTF stars with C07 stellar parameters and the squares the IRTF stars for which we determined their parameters. The red line is the one-to-one correlation. The blue and green lines mark the 1σ and 2σ confidence intervals, respectively.
