TL;DR: The Infrared Array Camera (IRAC) is one of three focal plane instruments on the Spitzer Space Telescope as mentioned in this paper, which is a four-channel camera that obtains simultaneous broadband images at 3.6, 4.5, 5.8, and 8.0 m.
Journal ArticleDOI

TL;DR: The Infrared Array Camera (IRAC) on the Spitzer Space Telescope is absolutely calibrated by comparing photometry of a set of A stars near the north ecliptic pole to predictions based on ground-based observations and a stellar atmosphere model as mentioned in this paper.
Proceedings ArticleDOI

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.
Journal ArticleDOI
Repeatability and Accuracy of Exoplanet Eclipse Depths Measured with Post-Cryogenic Spitzer

TL;DR: In this paper, the repeatability, reliability, and accuracy of differential exoplanet eclipse depth measurements made using the InfraRed Array Camera (IRAC) on the Spitzer Space Telescope during the post-cryogenic mission were examined.
Proceedings ArticleDOI
Intra-pixel gain variations and high-precision photometry with the Infrared Array Camera (IRAC)
James G. Ingalls,Jessica Krick,Sean Carey,Seppo Laine,Jason Surace,William J. Glaccum,C. Grillmair,Patrick Lowrance +7 more
TL;DR: In this paper, an adaptive centroiding and repositioning method (Peak-Up) that uses the Spitzer Pointing Control Reference Sensor (PCRS) to repeatedly position a target to within 1 IRAC pixels of an area of minimal gain variation was proposed.
