Figure 5: Temperature evolution of the local hz and α parameters i.e. the Se-height from the Fe-Fe layer and the Se-Fe-Se bond angle, respectively.

These parameters are determined using the measured bond distances. Error bars take account of the correlations beween the RFe−Se and RFe−Fe fit parameters. Cartoons showing definitions of the two parameters are also inserted. The dashed line in the lower panel is a guide to the eyes.
