我们推出了新的斯皮策红外阵列相机（IRAC）3.6和4.5 μm马赛克，涵盖三个领域：E-COSMOS、DEEP 2-F3和ELAIS-N1。我们的马赛克包括新的IRAC观测以及这些领域的再处理档案数据。这些字段是HSC-Deep grizy调查的一部分，并且具有丰富的附加辅助数据。这些新的IRAC镶嵌的增加是至关重要的，允许改善测光红移和恒星人口参数在宇宙中午和更早的时代。这项工作绘制的总面积为1.17 deg 2，平均积分时间为1.1200 s，在AB中3.6（4.5）μm处提供的中值5σ深度为23.7（23.3）。我们执行SExtractor光度测定的组合马赛克，以及单时代马赛克采取106个月的间隔。所得的IRAC数计数显示出与以前的研究很好的一致性。结合这些领域现有的和即将到来的分光光度数据，我们的IRAC马赛克将使广泛的星系演化和活动星系核的研究。考虑到这一目标，我们将这三个领域的综合IRAC马赛克和覆盖图公之于众。
We present new Spitzer Infrared Array Camera (IRAC) 3.6 and 4.5 μm mosaics of three fields, E-COSMOS, DEEP2-F3, and ELAIS-N1. Our mosaics include both new IRAC observations as well as reprocessed archival data in these fields. These fields are part of the HSC-Deep grizy survey and have a wealth of additional ancillary data. The addition of these new IRAC mosaics is critical in allowing for improved photometric redshifts and stellar population parameters at cosmic noon and earlier epochs. The total area mapped by this work is ∼17 deg2 with a mean integration time of ≈1200s, providing a median 5σ depth of 23.7(23.3) at 3.6(4.5) μm in AB. We perform SExtractor photometry both on the combined mosaics as well as the single-epoch mosaics taken ≈6 months apart. The resultant IRAC number counts show good agreement with previous studies. In combination with the wealth of existing and upcoming spectrophotometric data in these fields, our IRAC mosaics will enable a wide range of galactic evolution and AGN studies. With that goal in mind, we make the combined IRAC mosaics and coverage maps of these three fields publicly available.
