Reported Tc Timeline
Transition temperature versus year, one dot per reported measurement.

Transition temperature versus year, one dot per reported measurement.
Loading timeline data…
Reported transition temperature versus year, with the date basis, result origin, sample state, pressure, and source retained for each result. Marker colours identify families; symbols identify origins. This is neither a discovery-history chronology nor a world-record leaderboard. Legacy reports are not independently confirmed results.
Reviewed-only mode is unavailable until accepted result-level reviews exist. “Observed only” selects a reported result origin, not experimental confirmation or scientific approval.
The larger display takes longer to load. Coverage counts and reported record summaries use the full eligible selection in both views; sampling limits are shown below.
Unsampled response selection: 487 returned results from 487 eligible reported results. Method: complete. This display selection is not a statistically representative sample or an ML dataset.
Selected before pagination: 487. Strata represented: 14 / 14; omitted rare groups: 0. Policy: timeline-stratified/1.0.0.
Markers describe reported result origin, not scientific approval. Catalogue eligibility is governed separately; each hover includes its visibility status. Exact year/Tc overlaps are display clusters only: no results are merged. Click a marker or use the overlap selector below to inspect every received member. Server sampling may omit additional results at the same coordinates; cluster counts refer to this received selection. Years are not jittered.
All 487 received results are available here, including coordinate overlaps and results omitted by the SVG renderer budget. This table does not include results omitted by server sampling. Linked sources count bibliographic identifiers, not independent works. An occurrence count is not independent replication; legacy records remain unreviewed.
