Methods of Analyzing Temperatures in Post-Flare Loops using the XRT on Hinode
Abstract
The X-Ray Telescope on Hinode has unrivaled temperature coverage, with 9 X-Ray filters in the focal plane. Using 7 different filter combinations, XRT observed a C8.2 flare on July 10, 2007. We use two different methods to glean temperature information about the post-flare loop system in this event. First, we examine the flare loops using the combined filter ratio method, which is a ratio method that utilizes observations in multiple filters in order to optimize the signal quality. Secondly, we calculate temperatures based on a differential emission measure method, which is a forward fitting method of determining temperatures. The results of these two methods will be compared.
