libtcspc.TimeCorrelateAtFraction¶

final class libtcspc.TimeCorrelateAtFraction(fraction, use_start_channel=False, numeric_traits=None)[source]¶

Bases: Node

Processor that time-correlates detection pairs at a fractional position.

The emitted abstime is interpolated between the start and stop detections at the given fraction; the channel is taken from the stop detection by default, or the start detection if use_start_channel is true.

Parameters:

fraction (float or Param[float]) – Position between the start (0.0) and stop (1.0) detections.
use_start_channel (bool) – If True, use the start detection’s channel. Default False.
numeric_traits (NumericTraits or None) – Numeric traits for the emitted events. Defaults to NumericTraits().

Notes

Events handled:

DetectionPairEvent: emit a TimeCorrelatedDetectionEvent.
All other event types: pass through unchanged.
End of input: pass through.
