Statistics for synthetic C¹⁸O (upper row) and ¹³CO (bottom row) spectra. Histograms are plotted for the number of spectral peaks, the line width converted to standard deviation σ, the skewness, and the kurtosis. Each frame contains four histograms that correspond to R=1, 2, 8, and 32, in decreasing order of the histogram height.
