Figure shows some of the tested rates. We find the rates between 0.9×10 -4 and 1×10 -3 to best describe a cut between the sparse and the dense region. With a rate of 1×10 -3 , 569 molecules are detected as outliers while a rate of 0.9×10 -4 leads to a classification of 512 molecules as outliers. In the following we consider the contamination rate 1×10 -3 for further discussion. We argue that this list should not be seen as a fixed framework on strategic molecules, but as an ensemble of potentially useful molecules for present and future process developments.
