|Control||Theta||Phi||Peri||Red Galaxy Mass||Number of Stars||Friction||Big Halos|
|Function||Inclination Angle of each galaxy||Orientation Angle of each galaxy||Distance of Closest Approach||In terms of the Green Galaxy||Number of simulated points||Dynamical Drag between Stars||Extent of unseen dark matter|
Run 2 simulations which differ ONLY in one control setting. You may choose any of the controls listed above EXCEPT the number of stars. This only affects the quality of the simulation: using more stars looks better, but takes longer to run. For example, you might investigate what happens when you change the mass, or the distance of closest approach.
Record and report the control settings which you use. Which control did you change? From what to what? Describe the results of your simulations. How did things change when you altered the control setting?
