		| Abstract: | 
		We analyze the temperature distribution of the active region brightening observed
 by HINODE/XRT. The temperature structure is derived using various filter-ratio techniques and DEM analysis. The results are compared and it is found that the filter-ratio techniques are accurate only for relatively narrow DEMs. |
