![]() ![]() ![]() The following algorithms for calculating statistical ξ parameters are used to parameterise I(ν,T) arrays of temperature‐dependent Raman spectra: Pearson correlation coefficient characterising the similarity/difference of signals autocorrelation function, proposed earlier for estimating the weighted average width of spectral lines and skewness and kurtosis, the parameters of the distribution of signal intensity. For the diagnosis of spectral changes under the influence of an external factor, as well as for the determination of critical values, statistical methods for the treatment of the spectrum profile provide more accuracy than a peak‐fitting procedure. The application of statistical methods to Raman spectroscopy is due to the need to analyse arrays of poorly resolved mineral spectra having low symmetry, large unit cells, and so forth. ![]() Pentanummium 15-CI 66 Byzantine Empire, late V-early VI century AD Pentanummium 16-CI 256 Byzantine Empire, late V-early VI century AD (?) 17-CI 166 Byzantine Empire, late V-early VI century AD Pentanummium 18-CI 114 19-CI 269 Byzantine Empire, late V-early VI century AD Pentanummium 20-CI 5, Byzantine Empire, late VII-early VIII century AD semifollis 21-CI 116 Byzantine Empire, late V-early VI century AD Pentanummium ![]() Mint: Antioch, Officina "A" 2-CI 27 Eastern Roman Empire.
