Method and provenance

Production method
Native metadata identify NK.KKN BHZ/BHN/BHE channels at 50 Hz and IC.LSA BHZ/BH1/BH2 channels at 40 Hz. The declared 45-minute KKN request returned miniSEED; both LSA locations 00 and 10 returned HTTP 204 No Data.
Provenance
Coordinated and archived by EarthScope Consortium (formerly IRIS DMC) under International Federation of Digital Seismograph Networks (FDSN) data sharing agreements.
Validation
Source Identity And Access Assessed
Uncertainty
No 1-millisecond timing accuracy, calibration accuracy, full trace continuity, or event-specific signal interpretation was established. Instrument-response metadata alone does not demonstrate calibration accuracy.
Limitations
Station metadata alone does not establish waveform availability. The original network terms govern reuse; no CC0 grant was verified.
