SERVS: Spitzer Extragalactic Infrared Survey Catalog for Five Fields

SERVS provides deep infrared observations at 3.6 and 4.5 microns across five extragalactic fields. The catalog contains matched, high-reliability (>99.9%) objects detected in both bands with a signal-to-noise ratio greater than 10-sigma. This data was produced by NASA's Spitzer Space Telescope Exploration Science program.

Use Cases

• Selecting high-reliability extragalactic samples based on the >99.9% reliability criterion
• Analyzing infrared properties of galaxies based on matched 3.6 and 4.5 micron photometry
• Conducting statistical studies of galaxy populations across five deep survey fields
• Cross-matching with other multi-wavelength surveys using the high-confidence object positions

Strengths

• High object reliability (>99.9%) as stated in the description
• Observations conducted in two infrared bands (3.6 and 4.5 microns)
• Covers five established extragalactic survey fields (ELAIS-N1, Lockman Hole, XMM, ELAIS-S1, CDFS)

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 survey fields and instrument
