Frequency of the error, ${\mathrm{\Delta }}_{\mu }^{\alpha }$, between computed and observed ¹³C^α chemical shifts, for each of the 801 cysteine residues in cystines computed in this work, i.e., from all proteins listed in Table 1, except BPTI. The data were binned using an interval of 0.5 ppm, and then fit to a Gaussian function with a mean value x₀ = 0.12 ppm, and standard deviation σ = 3.69 ppm
