Interpretation of Stark broadening measurements on a spatially integrated plasma spectral line

In thermal plasma spectroscopy, Stark broadening measurement of hydrogen spectral lines is considered to be a good and reliable for electron density. Unlike intensity based measurements, measurements can pose problem interpretation when the light collected result spatial integration. Indeed, assuming no self-absorption emission lines, intensities simply add up but broadenings do not. order better understand results on our which has an unneglectable thickness, Python code been developed local thermodynamic equilibrium (LTE) assumption calculated composition properties. This generates simulated pseudo experimental (PE) H$\alpha$ line resulting from integration over thickness in selected direction given temperature profile. The density was obtained using PE different profiles. It resulted that this governed by maximum profile until exceeds 70% 80%
