SAGE (v3) MIPS 24um Matched Multi-Epoch Catalog & Full List Definition

SAGE Overview

The Spitzer Space Telescope Survey of the Large Magellanic Cloud Legacy Project Surveying the Agents of a Galaxy's Evolution (SAGE) traces the life cycle of observable matter that drives the evolution of a galaxy's appearance. SAGE has revealed over 6 million sources including ~150,000 evolved stars, ~50,000 young stellar objects and the diffuse interstellar medium with column densities > 1.2×1021 cm -2. The data will provide fundamental insights into the physical processes of the interstellar medium, the formation of new stars and the injection of mass by evolved stars and their relationships on the galaxy-wide scale of the Large Magellanic Cloud.

The SAGE project page can be found here. The survey is described in Meixner et al. (2006). (AJ, 132, 2268). Also provided with the data release is the SAGE data delivery documentation [PDF]

The Matched Multi-Epoch Catalog and Full List contains matches between the Epoch 1 and Epoch 2 Catalog and Full List, respectively. Both epochs are listed separately in the Epoch 1 and Epoch 2 Catalog and Full List. For a detailed discussion of the matching criteria, see Section 8.5 of the Data Delivery Document.
