论文摘要
我们提供了最新的评估和更新，应用于Keck I望远镜上的红外勘探（MOSFIRE）的多对象光谱仪。在整个整合过程中，当Mosfire以$ 4小时的价格坐在一个面具上时，已经测量了蒙版恒星的略微漂移。尽管这并不影响Mosfire进行的所有科学案例，但漂移可能会给观察者弄脏信号，这些观察者的科学目标取决于冗长的整合。该效果被确定为三个因素的可能结果：内部弯曲补偿系统（FCS），指导摄像头弯曲系统和/或不同的大气折射（DAR）校正。在这项工作中，我们将总结这三个系统，并仔细阅读当前的测试，以缩小此漂移的可能罪魁祸首，并强调将来的测试。
We present a recent evaluation and updates applied to the Multi-Object Spectrometer For Infra-Red Exploration (MOSFIRE) on the Keck I telescope. Over the course of significantly long integrations, when MOSFIRE sits on one mask for $>$4 hours, a slight drift in mask stars has been measured. While this does not affect all science-cases done with MOSFIRE, the drift can smear out signal for observers whose science objective depends upon lengthy integrations. This effect was determined to be the possible result of three factors: the internal flexure compensation system (FCS), the guider camera flexure system, and/or the differential atmospheric refraction (DAR) corrections. In this work, we will summarize the three systems and walk through the current testing done to narrow down the possible culprit of this drift and highlight future testing to be done.
