- is a merger containing a single stable class \(C^*\) on its ML list, the other spurious classes on the ML list will be combined with the class \(C^*\)
- In any other case the SC are labeled as noise and discarted.
The changes in the classes will modify the composition of the mergers, now some of them will have fewer members. All the merged classes with the same ML are equivalent and will be fused together. The other particular case isthe merge with just one related class, that mergers will be labeled as track of the same class. In the general case, this again creates the possibility of new equivalent mergers and it will need consecutive fusions until no more equivalent mergers are present. An example of the tracking that needs a class removal and fusion is shown in Figure \ref{748245}A. Finally, the remaining mergers are labeled correspondingly as a mixture of classes, to allow the track the activity of the class even when the quality of isolation is low.
