| Contains the data from the SAGE-SMC IRAC Combined Epoch Catalog v1.5. |
| The SAGE-SMC project is a Cycle 4 legacy program on the Spitzer Space Telescope. This catalogue contains 2,574,736 sources in the SMC with fluxes and magnitudes from the IRAC bands [3.6um], [4.5um], [5.8um] and [8.0um], and the 2MASS All-Sky PSC. The project overview and initial results are described in a paper by Gordon et al. (2010, in prep). For more details, see Section 3.3 of the SAGE-SMC Data Delivery Document. Required constraints:
