Figure 1.

An illustration on how CNA units are defined. Left: Consecutive CNA probes are merged into two intervals, with the first interval containing probes 1–10 and the second interval containing probes 14–16. Right: Each of the two intervals is split into CNA units according to the correction coefficients between CNA probes defined by Eq. (2), e.g., the first interval is split into three independent CNA units.
