Reading the viewer
Labels: 4, and only 4
EVERYTHING ABOVE, NOW CLICKABLE.
The viewer is the literal instrument panel for this pipeline — every layer, marker, and drawer maps to a step already covered in tutorials 01 through 06. This tutorial is a guided reading of it, plus the four honest labels every result on this site is allowed to carry. Nine tutorials, read in order — this is the seventh.
Unlike the Overview page, nothing on this page is invented. This describes the real pipeline — the same one the viewer, survey and cell browsers actually run.
Everything explained above is now something you can click.
The viewer is the literal instrument panel for this pipeline — every layer, marker, and drawer maps to a step already covered.
Color is never decoration here — it only appears where a pixel actually changed. Rather than re-explain every layer, marker and drawer a second time on this page, that explanation now lives in one place: the viewer's own guide — kept in sync with the real page, with real screenshots of the live interface, not a redrawn mockup of it.
Open the viewer guideTwo more browsers widen the view: one patch at a time, then everything at once.
05 The Cells browser
Groups ZTF's own repeat visits to one small patch of sky — a "cell" — and lets you step or blink through every visit to that same patch, aligned on one shared grid, with that visit's detections overlaid.
06 The Survey browser
The wide view across everything processed. Its one rule: recoveries, candidates, and verdicts stay in visually and textually distinct categories — never blended into one undifferentiated results list.
Four labels, and only four.
The honesty framing that governs every result this pipeline produces, wherever it's shown.
Recovery, candidate, verdict, unchecked.
A recovery is a real, already-catalogued object found blind and matched to a catalog. A candidate is an unconfirmed detection — mostly artifacts until a linker confirms it. A verdict is a classifier's real/bogus-plus-type call on an already-known source. An unchecked result is a catalog lookup that couldn't complete — styled neutrally, never treated as a negative.
No fifth category. This project has made zero novel discoveries and does not claim to. If you don't see a word for what you're looking at in the viewer, it isn't there.
Go watch it run.
Everything above is the real pipeline, explained in the order it runs. The browsers below are that same pipeline's actual output — a working ZTF difference-imaging system, not a mockup of one.
