We report an advanced numerical procedure for deconvolution of theoretical
asymmetric convolution integral of a Gaussian and a plasma broadened spectr
al line profile j(A,R)(lambda) for spectal lines. Our method determines all
broadening parameters, self-consistently and directly from the line profil
e with minimal assumptions or prior knowledge. This method is useful for ob
taining complete information on all plasma parameters directly from the rec
orded shape of a single line, which is very important in case no other diag
nostic methods are available. The method is also convenient for determinati
on of plasma parameters in the case of a symmetrical profile such as Voigt
one.
