Comparison between between G-virial_model and G-virial_{reconstructed} in the PPV space for the hydrodynamical model described in Sect. 5.2. In the model, turbulence is injected through compressible forcing, and no self-gravity is included (Federrath et al. 2008). The G-virial_model in the PPV space is defined as the mass-weighted average of the G-virial_model in the PPP space, which is defined in 12. Here, the grayscale image is the simulated ¹³CO(1–0) emission from the model. The red contours stand for the G-virial_model, and the contour levels are (6, 5, 10). The blue contours stand for the G-virial_{reconstructed}, and the contour levels are (3, 6). It worth noting that the G-virial_model and the G-virial_{reconstructed} agrees better at regions where mass is traced. This can be seen in the v = −0.2 km s^-1 channel. They agree better at the regions where mass is traced (e.g., the red arrow), but does not agree well at the region without mass (e.g., the blue arrow).
