Summary
If sample rates recorded in the miniSEED fixed header and channel metadata disagree by more than 1%, sample_rate_channel is 1 (TRUE). Otherwise it is 0 (FALSE).
Uses
sample_rate_channel will catch an inconsistency between metadata and time series that is easily corrected by resubmitting new metadata.
Data Analyzed
Traces – one N.S.L.C (Network.Station.Location.Channel) per measurement
Window – 24 hours starting at 00:00:00 UTC
Data Source – IRIS miniSEED archive or IRIS PH5 archive
SEED Channel Types – ?H?, ?L?, ?N?, ?G?, ?P? | High Gain, Low Gain, Accelerometer, Gravimeter, Geophone
Algorithm
- Request 24 hours of metadata and time series data for a single N.S.L.C.
- mseed sample rate is set to the sample rate of the first miniSEED record in this window
value = '1': abs(mseed sample rate - channel sample rate) > 0.01 | '0'
Metric Values Returned
value – ‘1’ (TRUE) if miniSEED and channels sample rates disagree by more than 1%; ‘0’ (FALSE)otherwise
target – the trace analyzed, labeled as N.S.L.C.Q (Network.Station.Location.Channel.Quality)
start – beginning of the data day requested (00:00:00 UTC)
end – end of the data day requested (truncated as 23:59:59 UTC)
lddate – date/time the measurement was made and loaded into the MUSTANG database (UTC)
