The X-ray Telescope (XRT) on board Hinode satelite has the capability to derive the temperature structure in the solar corona. We present the hieght dependence of the temperature above the limb. Because X-ray intensity above the limb is so faint, it is important to estimate the scattered light from disk corona. The eclipses happened on February 17 and March 19 in 2007 at Hinode orbit. On February 17, we took X-ray images above the south polar coronal hole, while Moon passed it. On March 19, we took the data for quiet Sun in the same way.
We can estimated the scattered light from the eclipse data, and derived the scatter-free X-ray images above the solar limb. In this meeting, we will present the temperatures above coronal hole and quiet Sun, based on the eclipse data.
