    33 '''Current summary of results:'''
    34 [[BR]]
    35 Up to this point we have focused on changing the following parameters (within the ranges stated in parentheses) for a ''jet'' traveling in a ''stratified and toroidal'' ambient medium:
    36 * Velocity of the jet (100 – 500 km/s)
    37 * Temperature of the jet (10 – 1,000,000 K)
    38 * Torus alpha (.3 - .9)
    39 * Torus beta (.2 - .8)
    40 * Ambient density (400 – 1,000 cm^-3)
    41 * Ambient temperature (1 – 100 K)
    42 We have also tested a jet in a constant ambient density, with a decreased ambient density and a clump in a normal stratified and toroidal ambient.
    43 [[BR]]
    44 
    45 __What works:__
    46 Through these runs we have found that the most significant changes occur when the velocity and temperature of the jet are changed. Moderate changes are made by changing the ambient density. 
    47 The shape of the ablation flow is most significantly affected by an increase in jet temperature. We see a widening of the central region that at higher speeds becomes more cylindrical, while a jet with a temperature of 10K seems to converge more to a point at the head of the jet.
    48 [[BR]]
    49 
    50 __What works a little:__
    51 Changes in the ambient density seems to affect some of the inner shape as well as affecting the instabilities.
    52 [[BR]]
    53 
    54 __What doesn’t work:__ Changes in torus alpha and beta only slightly change the bottom of the lobe (seeming to move it “up”) but do not change the shape of the lobe and changes in ambient temperature do practically nothing in changing the shape, density, or temperature distribution of the lobe.  ||
