SMUVS Source Catalog: Infrared Imaging of the COSMOS Field

The Spitzer Matching Survey of the Ultra-VISTA Deep Stripes (SMUVS) provides deep 3.6 and 4.5 micron imaging of three stripes in the COSMOS field. It catalogs approximately 350,000 sources detected at a point-source sensitivity of about 25.0 AB magnitude. The dataset was published by the National Aeronautics and Space Administration and was last updated on 2026-03-13.

Use Cases

• Conducting cosmological investigations based on the deep, uniform infrared sensitivity.
• Analyzing source populations and confusion based on the 4-sigma detection limit.
• Performing multi-wavelength studies leveraging the wide array of ancillary data available in the COSMOS field.
• Studying galaxy evolution and demographics based on the catalog of ~350,000 sources.

Strengths

• Contains approximately 350,000 sources, providing a substantial sample for analysis.
• Achieves a uniform and high sensitivity of about 25.0 AB magnitude at 3.6 and 4.5 microns.
• Covers a relatively large area within the well-studied COSMOS field.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is an approximate figure (~350,000); exact scale is unknown.
• Data may reflect observational bias inherent to the specific survey stripes and instruments used.
