Table 3. Correlation ρ_C of the cluster fluctuations for the first (M₁), the second (M₂) and the third (M₃) disjoint sets of the 24 human chromosome sequences. The fluctuations are anticorrelated with length, gene density, inter-chromosomal and intra-chromosomal segmental duplications, while they exhibit a positive correlation with the AT-rich regions. Very little correlation is found with the GC-rich regions and global AT composition. Length values are shown in the 2^nd column of Table 1. Gene density data are taken from Refs. ¹⁴, ¹⁵. Inter- and intra-chromosomal duplications data are taken from Ref. 14. Base compositions are shown in Table 1 (respectively 4^th–7^th columns for the whole sequence, 8^th–11^th columns for the first 10MBases, and in Tables S1–S6 of the Supplementary Information).
