It is often easy to detect and pick the first P onset times manually since the human eye can identify a change in amplitude or frequency in a signal even in the presence of high noise levels. The picking of S-phase onsets is more difficult because these onsets are often emergent and buried in the P coda, though at very short ranges the S onset can be impulsive...
