SERVS: Spitzer Extragalactic Infrared Survey ELAIS-N1 3.6 micron Catalog

The Spitzer Extragalactic Representative Volume Survey (SERVS) provides deep infrared observations of five extragalactic fields, including ELAIS-N1. This single-band 3.6 micron catalog from NASA contains objects with a signal-to-noise ratio cut at CSNR > 5 and a reliability flag REL=1. It was last updated on 2026-03-13.

Use Cases

• Cross-matching infrared sources with reliable near-infrared catalogs based on the single-band reliability flag.
• Conducting statistical studies of extragalactic objects based on deep 3.6 micron observations.
• Analyzing galaxy properties in the ELAIS-N1 field based on infrared photometry.

Strengths

• Data is from the Spitzer Space Telescope, a NASA mission.
• Catalog uses a signal-to-noise cut at CSNR > 5 and a reliability flag REL=1.
• Observations cover five extragalactic fields, including ELAIS-N1.

Limitations

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