AIA 171 Å image showing the artificial slits S1 and S2 used to study the oscillations on DF and RF, respectively. S1 has a width of 4 arcsecs, whereas S2 has a width of 10 arcsecs. The figure shows jet1 (white arrow) interacting with the filament. This jet will split the filament in two: DF and RF (see Fig. 1). However, this shows an early stage, and DF has not yet moved to its new position under the S1 slit. Part of the jet1 flows are directed in a NW direction along S2. The inset shows the white box area enlarged to show the details of the NW-bound jet.
