Velocity distribution of HI emission towards VRO 42.05.01 and OA 184. The data cube was taken from the CGPS. The radio contours at 143 MHz from the LOFAR map in this work are overlaid in white. The wedges in the upper left corner of each plot correspond to the velocity of each slice. The brightness temperature T_B colour scale is the same for each row and goes as indicated by the colour bar to the left of each row, but it is not the same between rows. The ranges are as follows: first row: 0 − 110 K; second row: 0 − 70 K; third row: 0 − 30 K; and fourth row: 0 − 20 K. We have saturated the emission from OA 184 (bottom) to highlight the fainter emission in the surroundings of VRO 42.05.01.
