libtcspc.PairOne¶

final class libtcspc.PairOne(start_channel, stop_channels, time_window, numeric_traits=None)[source]¶

Bases: Node

Processor that pairs each start with at most one stop per stop channel.

Like PairAll, but each buffered start is paired with at most one detection per stop channel.

Parameters:

start_channel (int or Param[int]) – Channel of the start detections.
stop_channels (Sequence[int]) – Channels of the stop detections.
time_window (int or Param[int]) – Maximum abstime difference for a pair (must be non-negative).
numeric_traits (NumericTraits or None) – Numeric traits for the events. Defaults to NumericTraits().

Notes

Events handled:

Detection events: paired as described above, emitting a DetectionPairEvent for each resulting pair.
All input events: pass through unchanged.
End of input: pass through; unpaired buffered start detections are discarded.
