Signatures of decayless oscillations in emission x − t maps and in the velocity components. Panel a presents signatures of oscillation-1 (from case-1). The top row in this panel displays a zoomed-in x − t map from Fig. 1, and the next three rows illustrate the time evolution of the velocity components v_x, v_y, and v_z, respectively. The horizontal white lines indicate the δx extent of the 3D volume from which the velocity components were obtained (see Sect. 4.1 for more details). The other two panels (b and c) present information for oscillations 2 and 3 in the same format.
