The ∼200,000 targets monitored for photometric variability during the Kepler prime mission include the best-studied group of stars in the sky, due both to the extensive time history provided by Kepler and to the substantial amount of ancillary data provided by other investigators or compiled by the Kepler team. To complement this wealth of data, we surveyed the entire Kepler field using the 3.6 and 4.5 μm bands of the Warm Spitzer Space Telescope, obtaining photometry in both bands for almost 170,000 objects. We demonstrate relative photometric precision ranging from better than ∼1.5% for the brighter stars down to slightly greater than ∼2% for the faintest stars monitored by Kepler. We describe the data collection and analysis phases of this work and identify several stars with large infrared excess, although none that is also known to be the host of an exoplanetary system. The final catalog resulting from this work will be available at the NASA Exoplanet Archive.

由于开普勒提供的广泛时间历史以及其他研究人员提供或汇编的大量辅助数据，开普勒主要任务期间监测的约 200,000 个目标包括天空中研究最充分的恒星群。开普勒团队。为了补充这些丰富的数据，我们使用 3.6 和 4.5 μ对整个开普勒场进行了调查暖斯皮策太空望远镜的 m 个波段，在这两个波段获得近 170,000 个物体的光度测量。我们展示了相对光度测量精度，从较亮恒星的优于~1.5% 到开普勒监测的最暗恒星的略大于~2%。我们描述了这项工作的数据收集和分析阶段，并确定了几颗具有大量红外线过剩的恒星，尽管其中没有一颗已知是系外行星系统的宿主。这项工作产生的最终目录将在 NASA 系外行星档案馆提供。
