Three typical time distance maps, corresponding to loop 1 from event 32, loop 4 from event 40, and loop 2 from event 48. The fits correspond to the detrending polynomial added to the sinusoidal fit and multiplied by the exponential damping profile for panels a) and b). The red points in panel c) were taken by eye to map out the oscillation and used for the subsequent fitting. The vertical blue bars represent the measurement of the initial displacement (a₀) and the initial oscillation amplitude (a_osc) of the upper loop edge.
