SERVS: Spitzer Extragalactic Infrared Survey Lockman Hole Catalog

Five extragalactic fields, including the Lockman Hole, were observed by the Spitzer Space Telescope's SERVS program. The catalog contains deep 3.6 and 4.5 micron infrared observations from the IRAC instrument. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Cross-matching galaxies with other infrared catalogs based on the deep single-band detections.
• Statistical analysis of extragalactic populations using the high-reliability single-band source lists.
• Studying galaxy evolution in deep fields using the 3.6 and 4.5 micron photometry.

Strengths

• Observations are from the Spitzer Space Telescope's IRAC instrument, a major NASA mission.
• Catalog is flagged for single-band reliability (REL=1) and uses a signal-to-noise cut (CSNR > 5).
• Data covers five major extragalactic survey fields, including ELAIS-N1 and CDFS.

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 single-band catalogs and are not required to have counterparts in the other IRAC band.
