libtcspc.MarkerEvent¶

class libtcspc.MarkerEvent(data_types=None)[source]¶

Bases: EventType

Event representing a timing marker or external trigger.

Used for frame, line, and pixel markers in scanning microscopy, and for other external trigger signals that the TCSPC hardware records alongside detections.

Parameters:: data_types (DataTypes or None) – Set of integer types parameterising the C++ event. None (the default) uses DataTypes defaults.

Notes

The corresponding C++ event has fields abstime and channel. When the hardware reports multiple simultaneous markers, one event is emitted per channel sharing the same abstime; the ordering among simultaneous markers is unspecified. The marker channel numbering may or may not share a namespace with detection channels, depending on the device.
