SAGE MIPS 160 Micron: Full Source List from Spitzer LMC Survey

The Spitzer Space Telescope SAGE Legacy Project surveyed the Large Magellanic Cloud to trace the life cycle of observable matter driving galactic evolution. The project revealed over 6 million sources, including approximately 150,000 evolved stars and 50,000 young stellar objects. This 'Full List' contains all extracted sources from the 160-micron MIPS mosaics, including spurious detections, and was last updated in March 2026.

Use Cases

• Searching for potential counterparts to known astronomical sources based on the full extraction list.
• Studying the life cycle of observable matter and galaxy evolution based on the survey's stated goal.
• Analyzing source reliability and detection criteria based on described signal-to-noise and correlation thresholds.
• Investigating the interstellar medium and star formation processes in the Large Magellanic Cloud.

Strengths

• Based on a major space telescope survey (Spitzer) with a clear scientific goal of tracing galactic evolution.
• Contains over 6 million sources, including approximately 150,000 evolved stars and 50,000 young stellar objects.
• Sources were extracted with defined quality criteria, including signal-to-noise >5 and point-like correlation thresholds.

Limitations

• The 'Full List' explicitly contains spurious sources, requiring user caution and filtering.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• A small subset of sources with unusual uncertainties was removed, and final catalogs may have <1% unreliable sources.
