Abstract

The Mexico-UK Submillimetre Camera for AsTronomy (MUSCAT) is a 1.1 mm receiver consisting of 1,500 lumped-element kinetic inductance detectors (LEKIDs) for the Large Millimeter Telescope (LMT; Volcan Sierra Negra in Puebla, Mexico). MUSCAT utilises the maximum field of view of the LMT's upgraded 50-metre primary mirror and is the first Mexico-UK collaboration to deploy a millimetre/sub-mm receiver on the Large Millimeter Telescope. Using a simplistic simulator, we estimate a predicted mapping speed for MUSCAT by combining the measured performance of MUSCAT with the observed sky conditions at the LMT. We compare this to a previously calculated bolometric-model mapping speed and find that our mapping speed is in good agreement when this is scaled by a previously reported empirical factor. Through this simulation we show that signal contamination due to sky fluctuations can be effectively removed through the use of principle component analysis. We also give an overview

部署前验证和预测的MUSCAT映射速度

墨西哥-英国亚毫米天文相机(MUSCAT)是一个1.1毫米接收器，由1500个集总元素动力电感探测器(LEKIDs)组成，用于大型毫米望远镜(LMT;墨西哥普埃布拉的内格拉火山)。MUSCAT利用了LMT升级后的50米主镜的最大视场，是第一个在大型毫米望远镜上部署毫米/亚毫米接收器的墨西哥-英国合作项目。使用一个简单的模拟器，我们通过结合马斯喀特的测量性能和在LMT观测到的天空条件来估计马斯喀特的预测映射速度。我们将其与先前计算的测热模型制图速度进行比较，发现当这被先前报道的经验因素缩放时，我们的制图速度非常一致。仿真结果表明，利用主成分分析可以有效地去除天空波动引起的信号污染。我们也会给出一个概述
