DEM analysis of the oscillating loop. (a) and (b): narrow-band EM images integrated in temperature ranges of 0.5−1.8 MK and 8−20 MK. (c): DEM profiles at three locations (P1, P2, and P3) inside the oscillating loop and at one location (P4) away from the oscillating loop. The yellow region outlines the EM and number density integration range for the oscillating loop. The error bars denote to the uncertainties (3δ) of the DEM solution.
