GLIMPSE 3D More Reliable Archive: Infrared Point Sources from Spitzer

GLIMPSE3D is a Galactic plane mapping project using the Spitzer Space Telescope Infrared Array Camera (IRAC). The More Reliable Archive provides higher-reliability point sources from the single-visit epoch 2, requiring two detections in adjacent bands. The data was produced by the National Aeronautics and Space Administration and was last updated on 2026-03-13.

Use Cases

• Studying vertical stellar structure based on the extended latitude coverage up to |b| < 4.2°
• Analyzing interstellar medium properties using infrared point source data
• Cross-referencing with 2MASS Ks band data for multi-wavelength analysis
• Investigating Galactic center features based on the dataset's focus on the inner plane

Strengths

• Focuses on higher-reliability sources by requiring two detections in adjacent bands
• Covers a large area of the Galactic plane with vertical extensions up to |b| < 4.2°
• Produced by the authoritative National Aeronautics and Space Administration

Limitations

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