摘要

Aditya-L1任务上的太阳紫外成像望远镜（SUIT）在200 - 400nm波长范围内观测太阳。本文介绍了各种地面和机载试验的结果，并与规范进行了比较。此外，我们还提出了数据校准方案。我们证明了测试结果符合指定的数字，除了空间分辨率。这种差异将限制光度测量，在2.2 “的尺度，而不是最初设想的1.4 ”。结果表明，SUIT观测为太阳观测打开了一扇新的窗口。

Test and Calibration of the Solar Ultraviolet Imaging Telescope (SUIT) on Board Aditya-L1

The Solar Ultraviolet Imaging Telescope (SUIT) on board the Aditya-L1 mission observes the Sun in the 200 – 400 nm wavelength range. This paper presents the results of various on-ground and on-board tests and their comparison with the specifications. Moreover, we also present the scheme for data calibration. We demonstrate that the test results are compliant with the specified numbers, except the spatial resolution. Such discrepancy will limit the photometric measurements only, at a scale of 2.2^′′ instead of 1.4^′′ as originally envisioned. The results obtained here show that SUIT observations open a new window for solar observations.

期刊介绍： Solar Physics was founded in 1967 and is the principal journal for the publication of the results of fundamental research on the Sun. The journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution to the outer corona and solar wind in interplanetary space. Papers on solar-terrestrial physics and on stellar research are also published when their results have a direct bearing on our understanding of the Sun.
