The following figures show photometric,mass and kinematic models for NGC3109 and NGC6822 (DDO47 comming soon)
The following figures show the circular velocity curve(continuous black), the predicted rotatio (red) and the actual observed rotation of NGC3109 and NGC6822 (dots).
We present here a comparison of the surface density in our model and the surface brightness in k band (Waldrake et al 2003) for NGC6822.
The first figure shows the H-I intensity map for DDO47. The second figure show the comparison between the H-I isophotes and the stellar component observed in R band. Figures courtesy of Walter and Brinks (2001).
