SDSS DR17 Photometric Survey of Stars, Galaxies, and Quasars

Photometric observations from the Sloan Digital Sky Survey Data Release 17. The dataset contains measurements of stars, galaxies, and quasars. The original survey was conducted by the SDSS collaboration.

Use Cases

• Classify celestial objects (stars, galaxies, quasars) based on photometric measurements.
• Train machine learning models for astronomical object detection from survey data.
• Analyze the photometric properties and distributions of different astronomical populations.

Strengths

• Data originates from the authoritative Sloan Digital Sky Survey (SDSS) collaboration.
• Covers three distinct and fundamental types of astronomical objects.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
