Parallax and Flux Ledgers

Parallax Index Inverts to Distance

A normalized parallax index is checked by its inverse distance index. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

A parallax index has an inverse distance index

The parallax index is 1/5. The checked distance index is 5.

The product is the source check

The product 1 confirms that this is a normalized inverse-index rule, not a parsec calibration.
