Konstantin Kartaschew

Hi Hugo,

I like the EstimatedBackground function in Mathematica 10.

see here: https://reference.wolfram.com/language/ref/EstimatedBackground.html

It uses basiacaly this algorithm:

Ryan, C.; Clayton, E.; Griffin, W.; Sie, S.; Cousens, D.: SNIP, a statistics-sensitive

background treatment for the quantitative analysis of PIXE spectra in geos-

cience applications. Nucl. Instruments Methods Phys. Res. Sect. B Beam Interact.

with Mater. Atoms 1988, 34; pp396–402.

Best,

Konstantin

Francois Perraut

Dear Hugo,

I agree with Konstantin. The SNIP algorithm works very well.

I also used the Vancouver algorithm that gives good results, which is fast and simple to encode. This algorithm is described in the article Zhoa et al., Appl Spectrosc. 2007 Nov; 61 (11): 1225-32.

Best Regards,

Francois

Hugo Garces

thanks for your answers
