WEAVE光纤定位器标高处的校准
Calibration at elevation of the WEAVE fibre positioner
摘要：
WEAVE是位于西班牙拉帕尔马的威廉赫歇尔望远镜的主要焦点的新宽场光谱设施。它的光纤定位器对于光谱仪的960光纤复用器的准确放置至关重要。我们提供了一个概述，最近的维护，弯曲的修改，并在天文台进行校准测量之前，最后的顶端组装。这项工作确保了我们对定位器在观测过程中改变方向时的行为有一个完整的了解。所有的光纤系统都经过了检查和修理，并且安装结构包含了新的夹具，用于安装内梁和牵引器支撑盘，现场板连接在牵引器支撑盘上。我们提出了最新的计量程序和结果，将在天空中验证。
英文摘要：
WEAVE is the new wide-field spectroscopy facility for the prime focus of the William Herschel Telescope in La Palma, Spain. Its fibre positioner is essential for the accurate placement of the spectrograph's 960 fibre multiplex. We provide an overview of the recent maintenance, flexure modifications, and calibration measurements conducted at the observatory prior to the final top-end assembly. This work ensures that we have a complete understanding of the positioner's behaviour as it changes orientation during observations. All fibre systems have been inspected and repaired, and the tumbler structure contains new clamps to stiffen both the internal beam and the retractor support disk onto which the field plates attach. We present the updated metrology procedures and results that will be verified on-sky.
