SeismicX-Cont License and Data-Use Clarification
SeismicX-Cont is a processed and structured HDF5-based continuous-waveform data product. It is derived from source waveform archives and event metadata, but it does not reproduce the original NCEDC or SCEDC archive organization and it is not an official waveform archive or network catalog.
Layer-specific terms

|---|---|
Processed HDF5 waveform database products in data/hdf5/ and waveform-derived mini subsets |
Distributed for non-commercial scientific research under upstream-compatible source-provider terms, including NCEDC-compatible CC BY-NC 4.0 conditions where applicable. The waveform arrays are not relicensed by SeismicX-Cont under CC BY 4.0. |

MIT License. |
| CEED-derived event and phase annotations | Distributed with source lineage retained. Users should cite SeismicX-Cont and the original CEED, SCEDC, NCEDC, and contributing-network sources as appropriate. |
| Optional automatic-pick outputs and consensus-candidate files | Validation and interoperability products. They are not ground truth and should be used with the same source-provider attribution and data-use constraints as the corresponding waveform-derived products. |
Provider clarification
Publication and redistribution of the processed HDF5 waveform layer have been clarified with the relevant U.S. seismic data providers. The release is intended for non-commercial scientific research, with documented preprocessing, transformation steps, HDF5 schema, metadata fields, and waveform-database construction procedures. The repository does not include provider-email text, dates, or quotations as part of the public license file.
Citation and reuse requirements
Users should cite the SeismicX-Cont full data-product DOI, the mini subset DOI when using the two-hour archive, and the original source data providers: SCEDC, NCEDC, CEED, and contributing seismic networks as appropriate.
