用光线追迹法推导STELLA的SES-VIS摄谱仪预期性能
Using raytracing to derive the expected performance of STELLA's SES-VIS spectrograph
摘要：
可见STELLA阶梯光栅摄谱仪（SES-VIS）是位于特内里费岛Izaña天文台的STELLA-II望远镜的新仪器。与原始的SES光谱仪（仍将用于近红外）和新的H& K优化光谱仪（目前处于设计阶段）一起，它将扩展STELLA的能力，跟踪太空任务（TESS，PLATO 2）的行星候选者。SES-VIS经过优化，可实现精确的径向速度测定和长期稳定性。我们开发了一个基于ZEMAX的软件包来创建模拟光谱，然后使用我们为PEPSI光谱仪开发的新数据简化包提取模拟光谱。本文的重点放在校准光谱，以及可用的校准源（平场，钍-氩和法布里-珀罗标准具）的全方位，一旦它们可用，可以与实际调试数据进行比较。并测试了环境参数变化对波长校准精度的影响。
英文摘要：
The visual STELLA echelle spectrograph (SES-VIS) is a new instrument for the STELLA-II telescope at the Izaña observatory on Tenerife. Together with the original SES spectrograph - which will still be used in the near IR - and a new H&K-optimized spectrograph, which is currently in the design phase, it will extend the capabilities of STELLA with the follow up of planetary candidates from space missions (TESS, PLATO2). SES-VIS is optimized for precise radial velocity determinations and long term stability. We have developed a ZEMAX based software package to create simulated spectra, which are then extracted using our new data reduction package developed for the PEPSI spectrograph. The focus in this paper has been put on calibration spectra, and the full range of available calibration sources (flat field, Th-Ar, and Fabry-Perot etalon), which can be compared to actual commissioning data once they are available. Furthermore we tested for the effect of changes of the environmental parameters to the wavelength calibration precision.
