2MASS ConeSearch: Two Micron All Sky Survey Catalog via MAST

All catalog holdings from the Two Micron All Sky Survey (2MASS) are accessible via a ConeSearch endpoint at the Mikulski Archive for Space Telescopes (MAST). The data is provided by the National Aeronautics and Space Administration and was last updated in March 2026. The specific volume of data, such as row count, is not detailed in the available metadata.

Use Cases

• Querying infrared source positions and photometry based on the all-sky survey coverage.
• Cross-matching astronomical objects with other MAST catalog holdings based on the ConeSearch service.
• Building training sets for star and galaxy classification models based on near-infrared photometric data.

Strengths

• Data originates from the authoritative 2MASS all-sky survey project.
• Access is standardized via the ConeSearch protocol, facilitating integration.
• Maintained by NASA and updated as recently as March 2026.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
