Figure 2

Deconvolution of the CL spectra in energy units obtained from SZ by using a Gaussian curve fitting. Measured spectrum shown by a black solid line; deconvoluted components by broken lines of blue one in the blue region and orange one in the yellow region; sum of the components by the red dotted line.
