AI总结：

摘要：
GHOST 是 Gemini South 8.1 米望远镜上新投入运行的光纤馈入式高分辨率光谱仪。它目前提供两种分辨率模式，由一个（或两个）输入 IFU 获取，视场为 1.2 角秒；在未分箱 CCD 条件下，光谱分辨本领分别为 56,000 和 76,000。在高分辨率模式下，还可启用同步 ThXe 校准灯；该灯与通过重构输入 IFU 图像而构建的同步伪狭缝轮廓相结合，将使精密视向速度测量成为可能。本文讨论了为实现完整排队观测运行而提出的路线图、潜在升级，以及影响最终在天 RV 精度的各项误差项；该精度估计处于 1–10 m s$^{-1}$ 范围。
英文摘要：
GHOST is a newly operational optical fiber-fed high-resolution spectrograph at the Gemini South 8.1m telescope. It currently offers the choice of two resolution modes captured by one (or two) input IFUs with a FOV of 1.2'' and a spectral resolving power of 56,000 and 76,000 for the unbinned CCDs. At the high-resolution mode, one can also instigate a simultaneous ThXe calibration lamp, which along with a simultaneous pseudo-slit profile constructed from reformatting the input IFU image will allow for precision radial velocity measurements. Here we talk about the proposed roadmap towards full queue operations, potential upgrades, and the error terms contributing to the final on-sky RV precision, which is estimated to be in the 1-10 m s$^{-1}$ range.
