Pantheon+ Supernovae Data for Expanding-Spacetime Cosmology Tests

Charles H. Ross created this dataset to test cosmological models using Pantheon+ supernovae observations. The data includes Excel files for parameterized calculations and TIF files for generated plots, supporting the manuscript 'Testing an expanding-spacetime cosmology with Pantheon+ supernovae and early-Universe constraints'. The dataset is 2.1 MB in size and was last updated on April 14, 2026.

Use Cases

• Testing expanding-spacetime cosmological models based on the described Pantheon+ supernovae data.
• Reproducing figures from the associated manuscript based on the provided TIF and XLSX files.
• Adjusting cosmological parameters for model fitting based on the Excel file's named parameter manager.
• Comparing model predictions with early-Universe constraints as referenced in the dataset's purpose.

Strengths

• Includes both tabular calculation files (XLSX) and generated image outputs (TIF).
• Dataset is openly licensed under CC-BY-4.0.
• Specific purpose is clearly stated for testing a particular cosmological model.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
