 * '''Diverging Wind: ''' This is the same setup as the jet, but instead of injecting gas directly along the y axis, it will sweep an arc of 10^o^.
 
-We also introduce toroidal magnetic fields in the MHD runs, which are initialized off the grid, according to the specifications in [http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1989ApJ...344...89L Lind et. al, 1989 ApJ]. We choose Rm = .6Rjet, or 300 AU, based on previous papers. This parameter measures how electric current flows along the jet. To determine initial field strength, we use the magnetic [[latex($\beta$)]] (not to be confused with [[latex($\beta_{t}$)]] which is associated with the shape of the torus), which is the ratio of the thermal pressure to the magnetic pressure. High values of [[latex($\beta$)]] will mean weak magnetic fields. For our initial runs, we chose [[latex($\beta = 1$)]].
