Velocity field of the clumps located at the waist of G319.88+00.79. These results are obtained by MALT90 with the HCO⁺ (1−0) transition. What is shown here is the central velocity from doing a Gaussian fit to the line; only pixels with a signal-to-noise ratio S/N ≥ 5 are shown here. The contours are for the column density (levels of 1, 1.5, 2, 3, 4.5, 7, and 8.5 × 10²² cm^-2). The 38″ beam of the MALT90 observations is at the lower left.
