class vallenae.io.TraRecord(time: float, channel: int, param_id: int, pretrigger: int, threshold: float, samplerate: int, samples: int, data: ~numpy.ndarray, status: ~vallenae.io.datatypes.HitFlags = <HitFlags: 0>, trai: int | None = None, rms: float | None = None, raw: bool = False)

Transient data record in tradb.

__init__()

Methods

__init__()
count(value, /)	Return number of occurrences of value.
from_sql(row, *[, raw])	Create TraRecord from SQL row.
index(value[, start, stop])	Return first index of value.

Attributes

channel	Channel number
data	Transient signal in volts or ADC values if raw = True
param_id	Parameter ID of table tr_params for ADC value conversion
pretrigger	Pretrigger samples
raw	data is stored as ADC values (int16)
rms	RMS of the noise before the hit
samplerate	Samplerate in Hz
samples	Number of samples
status	Status flags
threshold	Threshold amplitude in volts
time	Time in seconds
trai	Transient recorder index (foreign key between pridb and tradb)

classmethod from_sql(row, *, raw=False)

Create TraRecord from SQL row.

Parameters:

• row (Dict[str, Any]) – Dict of column names and values

• raw (bool) – Provide data as ADC values (int16)

Return type:

TraRecord

count(value, /)

index(value, start=0, stop=9223372036854775807, /)

Return first index of value.

Raises ValueError if the value is not present.
