Reproducibility of log intensities. This is a color-image presentation of a 36 by 36 square matrix. Each square block represents the squared Pearson correlation coefficient of log intensities (LIr2) for two series of intensity data scanned at two PMT settings. The diagonal represents self-self correlation. Red color means higher correlation, whereas green indicates lower correlation. Only 14 concentration series are used in the calculation of LIr2.
