Time-distance maps of the synthetic emission in the 171 Å line, for the three cases of oscillating loops, at the apex. Left column: SDO/AIA resolution. Middle column: Solar Orbiter/HRI_EUV resolution. Right column: MUSE/SG resolution. Top panels: Loop with the broadband driver. Middle panels: Loop with the sinusoidal, symmetric pulse. Bottom panels: Asymmetric, off-centre Gaussian pulse. Overplotted in each panel are the oscillating signal of the loop centre (black asterisks) and a fitted sinusoidal function (solid red line) with the four prominent frequencies for each signal, as detected by Auto-NUWT.
