Method. Figures are manufacturer reference specifications, not measurements. Every value is checked for unit consistency, physically possible magnitude, and plausibility for its equipment class before publication; figures that fail any check are withheld rather than shown, and figures reconstructed from related data are marked above. Imperial and metric figures are reproduced as published, except where a note states otherwise.
