(a) Formation of the pre-edge feature at 71.8 eV and decrease in the slope of the rising edge of the Al L2,3 spectrum upon approaching to the CCDX = 125 mm position. (b) Example of the derivative used for the slope analysis (first derivative of the spectrum, measured with the G1-3 grating in the first diffraction order at CCDX = 125 mm). Red lines indicate the borders of the range, within which the average value of the derivative and the error bar are calculated. |
