摘要:

我们提出了几个修正点源测光适用于数据的红外线阵列相机(IRAC)的斯皮策太空望远镜。由于IRAC阵列和光学器件的特性以及仪器在飞行中校准的方式,这些校正是必要的。当应用这些校正时,对于IRAC图像中足够信噪比的源,可以实现~2%的相对光度精度。

英文摘要:

We present several corrections for point source photometry to be applied to data from the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. These corrections are necessary because of characteristics of the IRAC arrays and optics and the way the instrument is calibrated in-flight. When these corrections are applied, it is possible to achieve a ~2% relative photometric accuracy for sources of adequate signal to noise in an IRAC image.
