What this measurement describes
Extent describes a region whose edge may be diffuse, chosen or model-dependent.

The number keeps its meaning.
How certain is the boundary?
The value depends on a scientific model or inferred boundary. It is not a directly touched physical edge.
What the engine actually divides
Vastoscope compares the SI value in metres for this representative bright-region diameter. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.
Familiar scale bridges
Give the number
something to stand beside.
These anchors are selected by logarithmic proximity from familiar human, engineered, planetary and cosmic references.

Evidence trail
Where this scale comes from.
Vastoscope keeps the displayed number separate from its measurement type and certainty. Representative and model-dependent values are intentionally labelled instead of presented as exact edges.
