SERVS: Spitzer Infrared Extragalactic Survey Catalog for ELAIS-S1

A single-band infrared catalog from the Spitzer Extragalactic Representative Volume Survey (SERVS) for the ELAIS-S1 field. It contains objects detected at 3.6 microns with a signal-to-noise ratio greater than 5 and high reliability. The data was produced by NASA's Spitzer Space Telescope Exploration Science program.

Use Cases

• Cross-matching extragalactic objects with near-infrared catalogs based on the high-reliability single-band detections.
• Performing statistical analyses of galaxy populations using the deeper, single-band catalog.
• Studying the infrared properties of galaxies in the ELAIS-S1 field based on 3.6 micron observations.

Strengths

• Data is flagged for high reliability (REL=1) and excludes low-coverage edge areas (POLY=1).
• Observations are from the Spitzer Space Telescope, a NASA mission.
• Catalog is deeper than the two-band high-reliability catalogs for single-band studies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect observational bias inherent to the specific SERVS survey fields.
