S/N pixel⁻¹ as a function of seeing (FWHM) for our SINFONI data cube simulated for a 2 hr exposure time. The lines correspond to a given SFR at z = 1.3 from SFR = 5 to 60 ﹩{\text{}}{M}_{\odot }\;{\mathrm{yr}}^{-1}﹩. The simulated cubes (generated from the hydrodynamical simulation) can be reasonably well fitted by our algorithm provided that the S/N pixel⁻¹ (at the central region) is greater than 3, irrespectively of seeing. This diagram applies to galaxies with inclinations around ﹩\sim 60^\circ ﹩.
