Hi all,

Could someone please answer my questions? I would really appreciate your help.

1. For linear combination fitting, there are three indicators for the goodness of fitting: R-factor, chi-square and reduced chi-square. Could anyone tell me how they work?

2. Since TEY is sensitive for the surface and FY for the bulk (and surface?), species detected by TEY should be also detected by FY, right?

3. How to calculate the maximum analysis depths for TEY and FY?

Thank you in advance.
