SERVS: Spitzer Infrared Survey of Five Extragalactic Fields

The Spitzer Extragalactic Representative Volume Survey (SERVS) catalog contains deep 3.6-micron infrared observations from NASA's Spitzer Space Telescope. It covers five extragalactic fields: ELAIS-N1, Lockman Hole, XMM, ELAIS-S1, and CDFS. The single-band catalog is optimized for depth and reliability, with objects selected at a signal-to-noise ratio greater than 5 and flagged for high reliability.

Use Cases

• Cross-matching galaxies with reliable near-infrared catalogs based on the deep, single-band infrared detections.
• Conducting statistical studies of extragalactic objects based on the high-reliability, single-band source list.
• Analyzing galaxy properties in five specific deep extragalactic fields mentioned in the description.

Strengths

• Observations conducted by NASA's Spitzer Space Telescope, a major space observatory.
• Covers five distinct extragalactic fields, providing a multi-field survey.
• Catalog is cut at a signal-to-noise ratio (CSNR) > 5 for reliability.
• Single-band catalog is deeper than the two-band high-reliability catalogs for maximum source detection.

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 five surveyed fields.
