Calculation method
Calculation method
Area-weighted mean PPFD
Sum reading×represented area / total represented area.
Minimum-to-mean uniformity
Minimum reading/weighted mean; zero mean reported0.
Area-weighted coefficient of variation
Weighted population standard deviation/mean.

Assumptions & limits
Assumptions & limits
- Grid PPFD readings, measurement areas. Returns Mean, minimum and uniformity measures. 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. Grid PPFD measurements (µmol/m²/s): minimum 0, maximum 1000000000000.0. Represented measurement areas (m²): minimum 1e-12, maximum 1000000000000.0.
