(a) PFY-XAS spectra of the Ce L-edge at T = 5 K (open circles). The size of the circles indicates the error bars. The red line is the total fit, the regions of different gray refer to the I(f 2), I(f 1) and I(f 0) spectral weights, taking into account a tanh-type background (black solid lines). (b) Temperature evolution of the Ce L3-edge spectra and the I(f 0) peak region on an enlarged scale. (c) Inset with 
as function of log(T). The relative error bars amount to ±0.25%. The black, dashed line is a guide to the eye, the red arrow indicates its inflection point which is taken as Kondo temperature TK.
