Abstract

We present a database of reduced data for all staring mode observations taken with the Infrared Array Camera (IRAC) during the Spitzer warm mission to monitor instrument performance, predict future instrument performance, and facilitate exoplanet and brown dwarf science. Our motivation is to be informed so that we can mitigate the impact of changing thermal conditions on science. Monitoring current trends allows us to predict future instrument performance and to adjust our recommended suite of best practices and calibrations accordingly. From this database we show that instrumental effects detrimental to high precision photometry either remain stable or improve. A uniform reduction of all IRAC light curves has never before been published, and will enable powerful science including accurate comparative studies of exoplanets and brown dwarfs. IRAC has been performing well throughout the warm mission and we expect performance to remain excellent.
