WISE 3-Band Cryo Atlas Metadata Table

NASA's Wide-field Infrared Survey Explorer (WISE) mission data from its post-cryogenic 3-Band Cryo survey phase, which scanned approximately 30% of the sky. The dataset is a metadata table containing processing information, tile center coordinates (RA, DEC), and derived statistics for Atlas images and the Source Catalog. It was last updated on 2026-03-13.

Use Cases

• Identify sky tiles for analysis based on provided RA and DEC center coordinates.
• Assess data quality for specific tiles using processing flags and derived statistics mentioned in the description.
• Filter tiles based on photometric parameters used for source extraction.
• Estimate source contamination by analyzing statistics on the number of sources affected by artifacts like optical ghosts.

Strengths

• Data originates from NASA's authoritative WISE space telescope mission.
• Covers approximately 30% of the sky during the 3-Band Cryo phase.
• Includes specific derived statistics like median pixel values and source counts with SNR > 3.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes much information is processing-specific and may not interest general users.
