APOGEE-derived parameters (x axis) versus ARGOS derived parameters (y axis) for the 204 reference set stars observed by both surveys. The bias (mean of the differences) and rms of the distributions are given in the upper left hand corner of each plot. The reference set stars that are within one ARGOS observational error, 0.13 dex (0.1 dex), from the maximum [Fe/H] ([α/Fe]) value reached by the reference set are plotted as blue crosses (red triangles).
