Horizon and profile source mapping

Skyline samples retain each original witness index, azimuth and elevation. Terrain sections retain each original range/height sample index. Dense samples are display points, not independent observations.

The research changed the question.

Inspect the control example, methodology and validation →

  1. R-01A · A negative result

    The original local terrain-uncertainty hypothesis was not supported at dGR203 for the tested decision. The negative control is part of the evidence.

    Original finding ↗
  2. R-01B · A different sensitivity

    Model-form sensitivity emerged, especially at dGR101. The separate historical dGR203 replication gap remained unresolved.

  3. R-01C · Native products tested

    The large dGR101 representation response survived native NASA terrain products. Removing domain clipping changed the earlier threshold interpretation.

What this evidence supports

Classification applies to this site + observable + analysis definition + evaluated model set. Duration differences describe model response; they do not establish which terrain representation is physically closest to the Moon.

  • Each horizon value interpolates bracketing rays; witness is a sampled/interpolated DEM point, not a direct measurement
  • Profiles use bilinear representations on an aligned ray; dense plot samples are not independent observations
  • Product104 MASK/BRES/DIFF semantics from original regional README; SIGM filename mapping to its GLD03 remains inferred
  • Ancillary support does not calibrate truth probability or measurement benefit

No fine-grid W* convergence was established. Pixel spacing is not independent terrain knowledge. Observer conventions are alternative analysis definitions.
