Corrected true thickness (m)
Core length × absolute dot(hole direction, bed normal).
Intersection angle to plane (degrees)
asin(abs(dot(unit hole,unit plane normal))).

Assumptions & limits
Assumptions & limits
- Core interval, hole orientation, bed orientation. Returns True-thickness estimate. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Core interval length (m): minimum 1e-12, maximum 1000000000000.0. Hole azimuth (degrees): minimum 0, maximum 360. Hole inclination from horizontal, down positive (degrees): minimum -90, maximum 90. Bed strike (degrees): minimum 0, maximum 360. Bed dip (degrees): minimum 0, maximum 90.
