Below full bounds each streak is a centred fraction of its measured range — a display transition, not a narrower measurement.

Each streak is one star's 1σ distance range along its line of sight. The geometry is measured; the colour and brightness are display responses to BP−RP and G magnitude.

How colour and brightness are drawn

Colour is a blackbody ramp keyed to observed BP−RP, uncorrected for interstellar reddening, so a reddened hot star reads cool. Intensity is a display response to G magnitude, attenuated with distance from the camera and divided along the smear; it is not photometry.
