Description
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.
Provenance

Collection Method
Observations from the Spitzer Space Telescope's IRAC instrument at 3.6 microns.
