Extended Data Fig. 6: Three example H I filaments of the G165 VHVC.

(a) Zoom-in images of the three filaments shown in Extended Data Fig. 4. (b) Slice in the l-VLSR plane, where l is the length along the ridge. (c) Slice in the l-r plane, where r is the radial offset from the ridge. (d) Radial intensity profiles (gray lines) and the mean profile (black line). The red dashed line shows the fitting result of the black line using a Gaussian function plus a first-order polynomial.
