TL;DR: In this paper, the authors summarize the in-flight scientific, technical, and operational performance of IRAC in two nearly adjacent fields of view on the Spitzer Space Telescope (SST) and show that IRAC is a four-channel camera that obtains simultaneous broad-band images at 3.6, 4.5, 5.8, and 8.0 μm.
