Pan-STARRS DR1: Wide-Field Astronomical Object Catalog via Cone Search

Data Release 1 from the Pan-STARRS1 survey, which used a 1.8-meter telescope and a 1.4 Gigapixel camera to image the sky in five broadband filters (g, r, i, z, y). The catalog is available through a cone search service hosted by MAST and was last updated on 2026-03-13. The survey was operated by the Institute for Astronomy at the University of Hawaii with funding from a consortium of 14 institutions.

Use Cases

• Identify and catalog stars and galaxies based on multi-band optical imaging.
• Perform spatial queries for astronomical objects using the cone search interface.
• Train machine learning models for object classification using photometric data from the five filters.

Strengths

• Data originates from a dedicated 1.8-meter telescope with a 1.4 Gigapixel camera, suggesting high-resolution imagery.
• Observations were made in five distinct broadband filters (g, r, i, z, y), enabling multi-wavelength analysis.
• Catalog is accessible via a standardized cone search service, facilitating programmatic access.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and instrumental bias inherent to the single Haleakala observatory site.
