Comparison of stellar population properties obtained with bases GM (vertical axis) and CB or BC (horizontal axis) for the 107 CALIFA galaxies. A one-to-one line is drawn in all the panels, as well as the best fit (dashed lines). The histogram inserted in each panel shows the differences in the property obtained with the base CB or BC with respect to GM. In the top-left corner of each panel, Δ is defined as the mean CB − GM (or BC − GM) difference, and σ_Δ is the corresponding standard deviation.
