IRS-TR 11001：红峰上升子阵的时间响应度变化
IRS-TR 11001: Temporal Responsivity Variations on the Red Peak-Up Sub-Array
摘要：
在斯皮策太空望远镜的低温任务过程中，根据对五颗标准恒星的分析，红外光谱仪（IRS）上的红峰子阵列的响应度变化了约2%。在前14次IRS活动后，敏感度下降了1.7%，然后在任务后期回升了1.0%。这些测量的不确定度优于~ 0.3%。标准星峰上光度的随机变化具有宽度约为2%的高斯分布，与系统时间变化的大小相似。
英文摘要：
Over the course of the cryogenic mission of the Spitzer Space Telescope, the responsivity of the Red Peak-Up sub-array on the Infrared Spectograph (IRS) varied by ~2%, based on an analysis of five standard stars. The sensitivity dropped 1.7% after the first 14 IRS campaigns, then climbed back up 1.0% later in the mission. The uncertainty in these measurements is better than ~0.3%. The random variations in the Peak-Up photometry of the standard stars has a gaussian distribution of width ~2%, similar to the magnitude of the systematic temporal variations.
