The map had one way to read a distance: the Range readout, a number for how far back the camera is. The local grid's five rings sat at 50 to 250 pc, fixed and unlabelled. They said nothing from inside a 2 pc hop, and nothing past 250 pc now that the Hipparcos stars Gaia places there are drawn. A scale bar now sits under the scale rail. It shows the longest round length (1, 2 or 5 x 10^n) that fits in 120 px, in AU inside a system and in parsecs or kiloparsecs outside. It is measured at the depth the view is centred on, since under perspective every depth has its own scale; under the plan view it is exact everywhere. The local grid's rings are now distances from the Sun, at a round step of about a fifth of the camera's distance and out past the camera: 50 to 350 pc from the opening view, 2 to 20 pc from twenty parsecs out. Each ring is labelled with its distance, on the side facing what the view is centred on, or across the far side of the grid when that is the Sun (the near side is under the camera and out of frame). The survey edge at 250 pc stays called out, as "Survey edge", whatever the step. The rounding lives in one place, scale-bar.ts, shared by the bar and the rings and tested there. Its formatter keeps three significant digits: one digit, enough for the bar's round lengths, printed the 250 pc ring as "300 pc".
