Derivation of DEM Distribution Using Yohkoh/SXT
Abstract
We present preliminary results of the DEM analysis for an active region seen in X-ray images. We apply the Withbroe-Sylwester method to estimate DEM distributions from X-ray images observed with Yohkoh/SXT, and obtain the DEM distribution in the temperature range of 2 MK to 10 MK. The DEM distribution of quiet loops in the center of the active region shows a power-law distribution with an index of 4--5.
