Loop tracing and DEM analysis of the three selected loops. The columns from left to right show the results of Loop #1, Loop #2, and Loop #3, respectively. Panels a–c: loop geometry (dashed line) and their widths (solid line) in 171 Å images. Panels d–f: temperature distribution along the loop geometry. Panels g–i: density distribution along the loop geometry. Panels j–l: width variation along the loop geometry. Panels m–o: goodness of the fitting.
