f8af0ec rewrote the neighbourhood note to say where positions come from, and it still said
"measured parallaxes" for everything but the archive's hosts. 313 HYG stars besides the Sun have
neither a Hipparcos nor a Gaia distance and sit at HYG's own, which for these rows is the Gliese
catalogue's resulting parallax: fetchStars says as much ("as often photometric as measured"), and
the review's cross-match with CNS3 (Gliese & Jahreiss 1991, VizieR V/70A; not repeated here)
found about 154 of them with a photometric or spectroscopic parallax, 130 within 25 pc — GJ 3522
drawn at 4.46 pc, 1000/224 mas, with no trigonometric parallax behind it. positionsNote now counts
the HYG stars without a distance error, the Sun aside, and names them. In the app on :4302 the note
reads "Positions from measured parallaxes; for the 313 stars only the Gliese catalogue places, from
its distances, about half of them photometric; for the 3,277 planet hosts only the NASA Exoplanet
Archive places, from its distances." and still fits the readout panel in four lines.
Test: a new star-readouts case counts a Gliese row and leaves the Sun out; the archive-only case
now expects the semicolon. Controls: dropping the Gliese clause, and counting the Sun among the
Gliese stars, each fail it.
