论文摘要
我们提供了开发的仿真工具，以帮助非常大型望远镜（VLT）的Cassegrain U波段有效光谱仪（立方体）的设计阶段，探索系统设计的各个方面并评估不同设计配置的性能。立方体的目标是在吞吐量方面是欧洲南部天文台（ESO）的“最终”紫外线（UV）仪器，目的是覆盖可从地面（300 nm至400 nm）的频谱中最蓝的部分，并具有最高的效率。在这里，我们介绍端到端（E2E）和曝光时间计算器（ETC）工具。 E2E模拟器已开发出不同的版本，以满足不同用户的需求，包括可以使用Jupyter笔记本访问更广泛的科学界使用的版本。系统团队使用E2E工具来帮助定义仪器的基线设计，以及在可能的低分辨率模式的科学评估中。 ETC是一种基于网络的工具，科学界能够通过该工具来测试多个立方体的一系列科学案例，证明了其潜力推动了检测特定紫外线功能的限制幅度，例如主要序列星中铍的丰度估计值。
We present the simulation tools developed to aid the design phase of the Cassegrain U-Band Efficient Spectrograph (CUBES) for the Very Large Telescope (VLT), exploring aspects of the system design and evaluating the performance for different design configurations. CUBES aims to be the 'ultimate' ultraviolet (UV) instrument at the European Southern Observatory (ESO) in terms of throughput, with the goal to cover the bluest part of the spectrum accessible from the ground (300 nm to 400 nm) with the highest possible efficiency. Here we introduce the End-to-End (E2E) and the Exposure Time Calculator (ETC) tools. The E2E simulator has been developed with different versions to meet the needs of different users, including a version that can be accessed for use by the broader scientific community using a Jupyter notebook. The E2E tool was used by the system team to help define the Phase A baseline design of the instrument, as well as in scientific evaluation of a possible low-resolution mode. The ETC is a web-based tool through which the science community are able to test a range of science cases for CUBES, demonstrating its potential to push the limiting magnitude for the detection of specific UV-features, such as abundance estimates of beryllium in main sequence stars.
