    26 Thickness option set to 0.1d smoothed density of disk boundary with ambient (r>3.9d0).

    29 Not exact 10 M,,j,, accountable from radius not being exactly 2e10cm.

     27Thickness option set to 0.1d smoothed density of disk boundary with ambient (r>3.9d0).[[BR]]
     28[[Image(wiki:hsediskruns:thick1.png, 600px)]][[BR]]
     29'''Thickness = 0.0d0'''
     30Obvious increase in mass.[[BR]]

     32Not 10 M,,j,, mass accountable from radius not being exactly 2e10cm and height not being 4e9cm.[[BR]]
     33* Actual radius = 3.984376*lScale=3.984376*5e9=~1.99e10
     34* Actual height = 0.781248*lScale=0.781248*5e9=~3.90e9
     35* Estimated density for a perfect disk = 3.7754 g/cc
     36Expected mass given the 3 quantities above: ~9.73M,,j,, which is pretty similar to what we observed.[[BR]]
     37'''Verdict:''' Mass readings are accurate, should change density to adapt to not exact disk dimensions, decision on thickness.
