WSTD: Calibration and Validation Data for a Wide-field Spacetime Topology Detector

651.6 KB of supplementary data supports the preprint 'WSTD — Wide-field Spacetime Topology Detector: Methodology and Multi-field Calibration'. The dataset likely contains post-processed statistical results for calibration and validation, including a rotation test dataset, a galaxy spectrum cross-validation sample, and a 10,000-sample null distribution for noise robustness assessment. It was authored by GenMin Li and published on figshare in May 2026.

Use Cases

• Calibrating a wide-field spacetime topology detection method based on the described rotation test dataset.
• Cross-validating galaxy spectrum analysis using the described cross-validation sample.
• Evaluating noise robustness in cosmological analyses based on the 10,000-sample null distribution.

Strengths

• Includes a specific 10,000-sample null distribution for noise robustness evaluation.
• Data is post-processed and ready for statistical analysis, not raw observational data.
• Published under a CC-BY-4.0 license, allowing for open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is 651.6 KB, indicating a limited scope of data.
