Deep Space 1

Measured quantities

Each row carries its own uncertainty and its own source. Where a row says no uncertainty is published, that is what the catalogue says — it is not a claim that the value is exact.

Trajectory, leg by leg

This object's parent frame changes over its life. Each leg names the frame it is expressed in and the source arc it came from. A leg with no geometry is a declared gap — the registry holds no path across it and draws none. This object has 32 legs; the table shows the first and last 12 and counts the rest.

What this registry does not know about it

These are absences in the catalogues aggregated here, not measurements of zero, and not statements that the quantity is unknown to science:

• no temperature
• no published uncertainty on any value
