摘要:

为了了解太阳大气层活动和加热的物理机制,光球层与日冕的磁耦合是日出观测的重要信息,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使我们能够研究磁耦合,其对准精度优于1弧秒。利用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,并证实了用我们的基线共对准方法可以实现太阳光学望远镜(SOT)和X射线望远镜(XRT)之间优于1角秒的共对准。本文介绍了从SOT和XRT CCD图像的精确对准校准的结果。

英文摘要:

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 arcsec. Using the Mercury transit observed on 8 November 2006 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 arcsec 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.
