Characterization of the Lateral Distribution of Fluorescent Lipid in Binary-Constituent Lipid Monolayers by Principal Component Analysis

Figure 5

Correlations between eigenvector elements and spectral characteristics. (a) Elements of the first eigenvector of the covariance matrix 𝑉_𝑗1 are plotted against the peak height of the respective spectrum. The slope and intercept of the fitted straight line are 1.1⋅10⁻⁴±4.5⋅10⁻⁶ and 0.012±0.005. The correlation coefficient is 0.96. (b) Elements of the second eigenvector of the correlation matrix 𝑉_𝑗2 are plotted against the half-width of the respective spectrum. The slope and intercept of the fitted straight line are 0.0019±0.00012 and −0.229±0.017. The correlation coefficient is 0.91.
