    • For Ward's method first each sample is considered its own cluster; therefore, the variance is null. Then, each following step will consider a pair of objects that can be fused while keeping the amount of variance as small as possible. This process repeats until a remaining supercluster is formed.

    • The theoretical discriminatory limit of a sensor array is given by the number of sensors in the array and the dynamic range of the detector. In the case of an array consisting in eight sensors (24 dimensions, where the grey pixel value has a range of 256 values (8-bit CCD, a sensor array should be able to generate up to 25624 patterns. A practical limit of discrimination (possible number of different patterns that the sensor array can possibly resolve) of our eight-sensor array can be estimated by considering that the changes of the grey pixel values for all sensors (RGB channels) in our data set average ∼30 units and assuming that changes in at least five channels are needed to obtain a discriminatory pattern. PCA shows that 10 PCs can describe 95% of the discriminatory data. We estimate that our sensor array should be capable of discriminating between (30/5)10, 610 patterns. This deduction of the practical discriminatory
    • 10 patterns. This deduction of the practical discriminatory limit is adapted from the method proposed in ref 36b by Suslick and Rakow.
