Event¶

class vallenae.processor.Event(hits, close_reason)[source]¶

Event data set produced by the EventBuilder.

An event represents the group of hits assigned to one acoustic-emission source by the Event Builder. Hits are time-sorted and the first hit (hits[0]) is always the Start-of-Event (SoE).

Methods

__init__(hits, close_reason)

Attributes

`channel_sequence`	Channels in the order they were hit (1.CH..n.CH in VisualAE).
`dt_to_first`	Time differences between the first hit and each subsequent hit in seconds.
`first_hit_channel`	First-hit channel (1.CH in VisualAE), equal to hits[0].channel.
`time`	Time of the Start-of-Event in seconds (= hits[0].time).
`hits`	Hits assigned to this event, time-sorted; hits[0] is the SoE.
`close_reason`	Why the event was closed.

hits: list[HitRecord]¶: Hits assigned to this event, time-sorted; hits[0] is the SoE.

close_reason: EventCloseReason¶: Why the event was closed.

property time: float¶: Time of the Start-of-Event in seconds (= hits[0].time).

property first_hit_channel: int¶: First-hit channel (1.CH in VisualAE), equal to hits[0].channel.

property channel_sequence: list[int]¶: Channels in the order they were hit (1.CH..n.CH in VisualAE).

property dt_to_first: list[float]¶

Time differences between the first hit and each subsequent hit in seconds.

Corresponds to VisualAE’s DT12..DT1n. Length is len(hits) - 1 (empty for a single-hit event).
