Main parameters vs. T_eff and log g discrepancies based on raw (first and third rows) and calibrated (second and fourth rows) values from the APOGEE−GALAH common data set. Horizontal axes indicate APOGEE DR17 data in all panels. Every data point is marked in the parameter planes, while the color-coding of stellar density starts from number two. The mean and standard deviation of the differences are also shown in each case.
