  A very simple method for determining the center (isomer) shift, CS, and the
spectral area, A, of a M\"ossbauer spectrum is outlined. Its applicability is
demonstrated in two examples viz. pyrite and a ternary sigma-phase Fe-Cr-Ni
compound. Sets of the spectra recorded in the temperature interval of 78-295 K
for the former, and 78-295 K for the latter were analyzed with the simple and a
standard method. CS(T)- and A(T)-data obtained with both ways of the spectra
analysis were analyzed in terms of the Debye model. The determined values of
the Debye temperatures agree well within the error limit with each other
proving that this very simple method is suitable for a quick determining of CS
and A spectral parameters.
