Error distribution for each RSM basis function. (a) Coefficient errors for data set 1. (b) Coefficient errors for data set 2. (c) RSM errors for data set 1. (d) RSM errors for data set 2. The markers have been placed over the corresponding theoretical quality factor from Fig. 4[link]. The errors in (a) and (b) were calculated by computing the overall Pearson correlation coefficient for each basis function coefficient when comparing the partial and full data sets. In (c) and (d) the correlation coefficients were computed for the RSM amplitude at each coordinate. The correlation factors for the coefficients and the RSM amplitudes are not the same, since the Gaussian radial basis functions of the basis set overlap. The dotted lines show great circles at longitudes 0°, ±30° and ±60° with the y-axis as the meridian. The dashed lines show small circles with elevations of 0°, ±30° and ±60° with the x-axis as the equator.
