All:

We are wondering if others agree that the reported values for the W L3 and W L2 edges are incorrect. We recently noticed the following:

The “Edge” – defined by the inflection point of the absorption edge step

When using the Ir L₃ edge (11215.0 eV) as a calibration, the W L₃- and L₂-edges are 10203.4 eV and 11542.4 eV, respectively.  

When using the Pt L₃ edge (11564.0 eV) as a calibration, the W L₃- and L₂-edges are 10203.3 eV and 11542.4 eV, respectively.

These observations are thus different than the reported values of 10207.0 eV and 11544.0 eV for the L₃ and L₂ edges, respectively.

Thanks in advance for the discussion and feedback.
