SVD decomposition (left panels), histogram of column correlations (center panels), and condition number of randomly subselected set of columns (right panels), for the eight described datasets. The results for a single medium/metal ion are shown on the top, and the results for the 3 media/metal ions are shown on the bottom. (A–D) The 35 largest singular values of the associated A matrices. (B–E) The distribution of the uncentered correlations between all pairs of columns in the A matrix, estimated by performing 20000 random samples. (C–F) The expected mean and standard deviation of the relative error for recovering population weights from an arbitrary M=1,…,10 subset of columns.
