Abell 1763: Infrared Source Catalog from Spitzer MIPS 70 Micron Imaging

733 infrared sources detected in the Abell 1763 galaxy cluster field using Spitzer's MIPS 70 micron instrument, where approximately 30% of the area lacks coverage in other key infrared bands. The catalog was matched against the 2MASS Point Source Catalog, but only about 7% of the sources have associated near-infrared magnitudes. This dataset was published by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Identify and analyze infrared-bright sources in a galaxy cluster based on the 70 micron MIPS imaging.
• Study the properties of sources lacking multi-wavelength coverage based on the description of areas without 24 micron, IRAC, or 160 micron data.
• Cross-match and compare infrared source populations with near-infrared catalogs based on the mention of 2MASS associations.

Strengths

• Focuses on 733 specific sources in a region with incomplete multi-band coverage, providing a targeted catalog.
• Integrates data from multiple instruments, including Palomar optical and Spitzer IRAC/MIPS, as mentioned in the description.
• Covers a field of approximately 40' × 40' with deep 24 micron imaging to a 5-sigma depth of 0.2 mJy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Only about 7% of the catalog's 733 sources have associated 2MASS near-infrared magnitudes.
