SERVS ELAIS-S1: Spitzer Infrared 4.5 Micron Galaxy Catalog

The Spitzer Extragalactic Representative Volume Survey (SERVS) conducted deep infrared observations of five extragalactic fields. This catalog from the National Aeronautics and Space Administration contains 4.5 micron data for the ELAIS-S1 field, with objects selected for high single-band reliability. It is designed for statistical studies or matching with external catalogs.

Use Cases

• Cross-matching galaxies with external near-infrared catalogs based on the high-reliability single-band detections.
• Statistical studies of galaxy properties in the infrared based on the deep, single-band observations.
• Analyzing the distribution of galaxies in the ELAIS-S1 field based on the survey's defined coverage area.

Strengths

• Data originates from the Spitzer Space Telescope, a major NASA observatory.
• Catalog is cut at a signal-to-noise ratio (CSNR) > 5 for reliability.
• Focuses on the ELAIS-S1 field, one of five deep extragalactic fields surveyed.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Objects are from a single infrared band (4.5 micron) only.
