Horizons (target depths)

Horizon opacity 95 %

Dropping the opacity makes the horizons see-through so the acquisition geometry and the zones stay readable underneath.

What the colours mean

lowhigh

Colour is the CRP hit count — the number of P-P ray legs that hit the horizon in each cell. It is the illumination fold proxy: higher means better sampling and SNR.


Summary


Cost of the constraint

Measured on the same 100 m grid every configuration shares, so a difference is always caused by the configuration, never by a moving colour scale.

Before — K1 normal

After — K2

The three configurations

Exported from the Wailawi 3D editor as wailawi_K1_normal.json, K2_kilang.json, K3_all.json. The same point sets drive the ray tracing on the other tabs.

Acquisition geometry

Active vs dropped stations in UTM 50S — the exclusions carve holes out of both the source and the receiver spread.

Surface energy — source side and receiver side

Every surfaced ray weighted by R², the squared P-P reflection coefficient at UBI (1.0 for head waves). Maps: UBI, 100 m cells. Bar charts: totals per horizon, both sides.
