Upper panel: observed abundance pattern of HIP 68468 versus condensation temperature before GCE corrections. The solid line is a fit taking into account the total error bars. It has a significance of 5.4σ, and the element-to-element scatter from the fit is 0.017 dex, which is larger than the average error bar (0.012 dex). Lower panel: abundance pattern after GCE corrections to the solar age. The error bars also include the error of the GCE corrections, and has an average of 0.014 dex. The correlation with condensation temperature is now stronger and more significant (6.0σ), and the element-to-element scatter about the fit (0.014 dex) is in perfect agreement with the average error bar.
