Measurements and fittings of the three selected coronal loops. The columns, from left to right, represent Loop #1, Loop #2, and Loop #3, respectively. Panels a–c: location of the coronal loop. The green solid line shows the path of the loop. Panels d–f: oscillation profiles. The green filled dots are the sampling points of the oscillation profile. Panels g–i: fitting results. The red points with error bars are the aforementioned data points, the blue solid line is the fitting model and the orange region is the confidence band of 95%.
