Single channel VGPS image at the velocity of peak associated 13CO emission. The contours are of integrated 13CO intensity, W13CO. Tick marks on the contours point towards decreasing values of W13CO.


Spectra from the 75% threshold criterion.

Spectra from the 85% threshold criterion.

The grey spectrum is HI from the VGPS and black spectrum is 13CO from the GRS. The black vertical line marks the peak 13CO velocity and the dashed vertical line marks the tangent point velocity.
