What this measurement describes
The selected line passes through the object from one side to the other. Where a body is not perfectly spherical, the catalog states which diameter is represented.

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 cloud diameter. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.

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.
