# Rs Network C3

`GET /api/v1/rs-network/c3/{region}`

## Request

- Auth: none declared

Run C3 cross-correlation analysis for an RS network region.

C3 (Stehly et al. 2008) samples all azimuths via equipartitioned
        coda. NOTE: the "faster convergence / fewer stations" claim previously
        made here is UNSUPPORTED and is contradicted at regional scale -- Zhang,
        Feng & Ritzwoller (GJI 2020) measured coda-wave C3 needing ~510
        source-stations for modest SNR and landing 3-5x WORSE than two-station.
        Untested in this regime; treat as a research path, not a capability.
        Returns velocity maps, dispersion, and site classification.
