SAGE MIPS 70 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 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 70-micron mosaics, including potential spurious detections.

Use Cases

• Cross-matching potential counterparts to known astronomical objects based on the full extraction list.
• Studying the distribution and properties of evolved stars in the Large Magellanic Cloud.
• Investigating young stellar object populations and star formation processes in a nearby galaxy.
• Analyzing the diffuse interstellar medium with column densities greater than 1.2×10^21 cm^-2.

Strengths

• Over 6 million sources identified, providing a large-scale view of the galaxy.
• Includes approximately 150,000 evolved stars and 50,000 young stellar objects, enabling population studies.
• Sources were filtered with signal-to-noise values >5 and point-like correlation criteria, suggesting a focus on reliability.

Limitations

• The full list contains spurious sources, as noted in the description.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
