Fig. 1.
Top panel: snapshot of our region of interest observed by SDO/AIA at 01:00:12 UT. The origin of our slit corresponds to (x, y) = (−1111, −366) arcsec. Bottom panel: time-distance map of a bright coronal loop exhibiting clear transverse oscillations with a dominant periodicity of ∼13 min. The dashed green lines highlight the two pixel locations used for further analysis.
