	Real data	1 ppm	2 ppm	5 ppm	10 ppm	20 ppm	100	1000	10,000	Random
Clusters	2472	2254	2040	1660	1365	1113	470	53	35	19
Explained distances	25,370	22,988	21,094	16,966	13,213	10,003	3261	328	213	115
% Excess over random	100	90.5	83.1	66.7	51.9	39.2	12.5	0.8	0.4	0

Uniformly distributed random noise of the indicated size was added to all observed masses and the network reconstructed as described in the text.
