Results of the simulated data sets of a star-forming disk galaxy at z = 2 after beam smearing using different relationships for the velocity dispersions. Shown are the distribution of the Hα surface brightness (left), velocity field (middle) and velocity dispersion map (right). In the upper row, we have simply taken the velocity dispersions as estimated from the N-body/SPH simulation, while for the lower row we assumed a relationship between the velocity dispersion and star-formation intensity of the form  km s^-1. The circle in the upper right of each plot represents the FWHM of the PSF used to make the artificial data set. The scales are in arcsec. We note that we have scaled the images such that the sizes of these panels and those in Fig. 5 are similar, for ease of direct comparison.
