Remark | Clusters were generated by the QT clustering algorithm. The algorithm assembles a series of clusters ordered by size, largest first, with no limit on the number of clusters other than the coherence (cluster diameter) defined a priori (0.7 in our clusters). To ensure robust clusters the distance metric used for clustering was 1-Ravg , where Ravg was the average Pearson correlation coefficient between moving average profiles over 20 realizations of the data plus simulated noise. Noise was generated by a two-component model consisting of an additive Gaussian background with standard deviation 2 ppm, and a multiplicative Gaussian sampling error with s.d.=0.1. Simulated data were floored at 1 ppm. | ||
