Where the numbers come from
Wherever a size follows from a definition, the chart is calculated from that definition and then compared with published values. Where sizes are only a convention, the page says so and names who published the values.
A chart is left out when its sources contradict each other or cannot be checked. A missing chart is better than a wrong one.
