日之出 X 射线望远镜提供了前所未有的 X 射线日冕观测，部分原因在于其高分辨率。 X 射线点扩散函数 (PSF) 在发射前在 NASA X 射线校准设施进行测量，半高宽为 0:008。本文描述了利用行星凌日和日食的在轨观测来验证 PSF 测量的工作。对水星凌日的分析得出 PSF FWHM = 1:000 0:0012。
The Hinode X-ray Telescope provides unprecedented observations of the solar corona in X-rays, due in part to its fine resolution. The X-ray point spread function (PSF) was measured before launch at the NASA X-ray Calibration Facility to have a FWHM of 0:008. This paper describes the work to verify the PSF measurements using on-orbit observations of planetary transits and solar eclipses. Analysis of a Mercury transit gives a PSF FWHM = 1:000 0:0012.
