Correlations after renormalizing the expression measures using the pairwise loess normalization on the probe set level. Except for the second normalization step, this is identical to the lower half of Figure 2, including the scaling of the axis to facilitate the comparison. The MAS5 values appear now well normalized throughout, whereas RMA and MBEI still show a similar pattern of residual correlation, although on a clearly reduced level.
