Assumptions & limits
Assumptions & limits
- True dip, strike-to-section angle. Returns Apparent dip. 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. True dip (degrees): minimum 0, maximum 89.999. Section azimuth minus strike (degrees): minimum -360, maximum 360.
