为了了解太阳大气活动和加热的物理机制，从光球层到日冕的磁耦合是来自Hinode观测的一条重要信息，因此需要在不同望远镜获得的数据之间进行精确的位置对准。Hinode航天器及其机载望远镜的开发是为了使我们能够研究磁耦合，共对准精度优于100。根据2006年11月8日观测到的水星凌日和每周定期进行的共对准测量，我们确定了精确图像共对准所需的信息，并证实了利用我们的基线共对准方法，太阳光学望远镜(SOT)和X射线望远镜(XRT)之间可以实现优于100的共对准。本文给出了对来自SOT和XRT的CCD图像进行精确共对准的定标结果。
To understand the physical mechanisms for activity and heating in the solar atmosphere, the magnetic coupling from the photosphere to the corona is an important piece of information from the Hinode observations, and therefore precise positional alignment is required among the data acquired by different telescopes. The Hinode spacecraft and its onboard telescopes were developed to allow us to investigate magnetic coupling with co-alignment accuracy better than 1 00 .U sing the Mercury transit observed on 2006 November 8 and co-alignment measurements regularly performed on a weekly basis, we have determined the information necessary for precise image co-alignment, and have confirmed that co-alignment better than 1 00 can be realized between Solar Optical Telescope (SOT) and X-Ray Telescope (XRT) with our baseline co-alignment method. This paper presents results from the calibration for precise co-alignment of CCD images from SOT and XRT.
