We produce the rst interferometric maps of the galaxy HI distribution and dynamics and use these maps to measure important quantities such as total HI mass, velocity width, and size. We create a dynamical model of the galaxy using a three-dimensional modeling technique. The rotation curve was obtained by tting a 3D tilted ring model to the HI data cube of galaxy IC 4710. The dynamical modeling of IC 4710 is being done for the rst time. We compare the model to the data cube to check for accuracy and found that they are in good agreement; this shows that the results are reliable. The obtained rotation curve is rising steeply until it reaches the maximum rotation velocity of 24.6 km s􀀀1 at a radius of 100 arcsec.enDwarf galaxyPhysicsUniverseScience experimentUniversity of Western Cape
