Dear all,
In the section, Choosing a Reference.
I just couldn’t find the traces mentioned in the block-
For example, in the following trace, the black section doesn’t shift in time, making it a poor choice. Meanwhile, the purple section does shift in time, but isn’t unique: it’s very likely that it will match with another part of the trace. The blue selection, however, is both unique and moves in time.
Where are these color sections?
