Pan-STARRS DR1: Filtered Astronomical Object Catalog with 2 Billion Rows

Pan-STARRS Data Release 1 Object Catalog "Best" filtered is a subset of the Pan-STARRS1 (PS1) survey data. The PS1 survey imaged the sky in five broadband filters using a 1.8-meter telescope and a 1.4 Gigapixel camera at Haleakala Observatories in Hawaii. This filtered catalog contains approximately 2 billion rows, based on objects having more than 2 detections, and is available via a cone search through the MAST archive.

Use Cases

• Identify and catalog celestial objects based on multi-filter optical imaging.
• Perform statistical analysis of astronomical object populations using the large-scale row count.
• Conduct cone searches for specific regions of the sky via the MAST service interface.
• Study object detection reliability using the 'more than 2 detections' filtering criterion.

Strengths

• Approximately 2 billion rows, indicating a large-scale astronomical catalog.
• Data originates from the Pan-STARRS1 survey, a dedicated wide-field imaging system operated by a consortium of 14 institutions.
• Observations were made in five specific broadband filters (g, r, i, z, y), providing multi-wavelength data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is an approximate figure ('~2billion'); exact scale may require verification.
• Description metadata is limited; actual data quality and completeness require manual inspection after download.
