Taurus Catalog: Spitzer Telescope Infrared Photometry of 269,358 Point Sources

269,358 point sources from the Spitzer Space Telescope survey of the Taurus Molecular Clouds. The catalog provides flux densities in the 3.6, 4.5, 5.8, 8.0, and 24 micron bands, with some sources also having 70 micron data. It was produced by NASA as part of the Taurus Spitzer Legacy project, with the last metadata update recorded in March 2026.

Use Cases

• Identify and classify young stellar objects based on infrared flux densities.
• Analyze spectral energy distributions of point sources using multi-band photometry.
• Study the structure and population of the Taurus star-forming region.
• Train machine learning models for source classification using infrared photometric features.

Strengths

• Catalog contains 269,358 point sources, providing a substantial sample for analysis.
• Photometry is provided at multiple aperture radii for IRAC sources and includes PSF-fitting for MIPS data.
• Covers approximately 44 square degrees of a well-known star-formation region.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the full survey area is unknown, which may limit suitability assessment.
