The model presented in this paper have been obtained after a number of iterations fixing the different free parameters. Here we show two models based on one single exponential emission line disk, both reproducing the observations to different degrees of satisfaction (Fig. A1 showing Model 1, and Fig. A2 showing Model 2 as described in the text). Although the second model could be seen somewhat comparable to that shown in Fig. 7, we chose Fig. 7 as our preferred model since it reproduces most of the observed flux and kinematic features of NGC 1358.
