Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For ISMB 600 the computed area agrees with the published value to 0.01% and Ix to 0.23%. Where a value is also published, the published one above is the one to quote.
