AI 中文摘要
本文介绍了塔尔图天文台光纤馈入式阶梯光栅光谱仪（TOFES）的数据处理管道。TOFES安装在折轴室中，将通过四通道仪器适配器连接到塔尔图天文台1.5米AZT-12望远镜，安装在望远镜的卡塞格林焦点处。该光谱仪的平均光谱分辨率为30000，单次曝光覆盖390至900纳米的波长范围。基于PyReduce包开发的数据处理管道已在太阳光谱上进行了测试。我们还介绍了Spectroscopy-Toolbox包，该包旨在为径向速度测量提供诊断和谱线认证的附加工具。该光谱仪将解决一系列科学问题，包括赫比格Ae/Be星的恒星表征以测量原行星盘的吸积污染、系外行星宿主恒星的表征（包括Ariel空间任务目标），以及大质量恒星大规模大气变异性的径向速度监测。
英文摘要
We introduce the data reduction pipeline for the Tartu Observatory Fiber-fed Echelle Spectrograph (TOFES). TOFES is installed in the Coudé room and will be connected to the 1.5 m Tartu Observatory AZT-12 telescope through a four-channel instrument adapter to be mounted at the Cassegrain focus of the telescope. The spectrograph has an average spectral resolution of 30,000 and covers the 390 to 900 nm wavelength band in a single exposure. The data reduction pipeline, based on the PyReduce package, was tested on spectra of the Sun. We also present the Spectroscopy-Toolbox package, which was developed to provide additional tools for diagnostics and spectral line identification for radial velocity measurements. The spectrograph will address a range of scientific questions, including the stellar characterisation of Herbig AeBe stars to measure accretion contamination from their protoplanetary disks, the stellar characterisation of exoplanet host-stars including the Ariel space mission targets, and radial velocity monitoring of large-scale atmospheric variability in massive stars.
