DEM results of the target coronal loop. a–d: narrow-band EM maps integrated in the temperature ranges of 0.32 MK−0.56 MK, 0.63 MK−1.12 MK, 1.26 MK−2.24 MK, and 2.51 MK−3.98 MK. e: DEM profiles at seven selected positions (1−7) along the loop and in one location (0) away from the loop. The color corresponds to the positions labeled in panel b. For clarity, panel e only draws the error bars at loop position 4. The gray region indicates the EM integrated range.
