Table 1

The additional parameters of the secondary Fourier fitting.

Number of Raman spectrum	The value of 𝐿opt from decomposition (9)	The value of 𝐴0 (d) from decomposition (9)	The value of the fitting error (%)	Pearson correlation coefficient (PCC)
RS (ba), 𝑑=0	9,97637	56,4327	0,19051	0,99976
RS (425C) 𝑑=1	10,0937	40,5278	0,25801	0,9998
RS (475C) 𝑑=2	8,92004	28,021	0,35399	0,9996
RS (575C) 𝑑=3	9,859	18,0758	0,38478	0,99938

It is interesting to note that the values in columns 3 and 4 have the monotone behavior and so this peculiarity can be used for calibration purposes.
