SIMPLE: Infrared Photometry Catalog for the Extended Chandra Deep Field South

Deep IRAC observations covering a 0.5 x 0.5 degree area surrounding the GOODS CDF-South field. The data was collected by the Spitzer Space Telescope as part of the SIMPLE Public Legacy Survey and is provided by the National Aeronautics and Space Administration. The catalog was last updated on March 13, 2026.

Use Cases

• Cross-match galaxy properties based on deep infrared observations mentioned in the description.
• Study galaxy evolution in a low-background region based on the survey's deep, multi-wavelength coverage.
• Conduct cosmological analyses based on the field's extensive supporting data from X-rays to thermal infrared.

Strengths

• Covers a 0.5 x 0.5 degree area with deep, several-hour-per-pointing IRAC observations.
• Targets a region described as having the best supporting multi-wavelength data for a cosmological survey field of its size.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
