This plot illustrates the dependence of the estimates of the latent intensities on the scan-2 and scan-3 readings in a situation in which the scan-1 readings were saturated. 120 randomly selected genes with scan-1 measurement close to 65 535 are shown by a (nearly) horizontal line. Corresponding measurements from scan-2 and scan-3 are also plotted. The estimates of the latent intensities (posterior median) corresponding to these 120 spots are shown in dots and connected by dotted line. All measurements are on natural scale.
