State conversion errors for a certain non-default orbit

    Details

      Description

      Load the default mission and open up DefaultSC. Set the Cartesian state to:

      X: -60072.4832989428
      Y: -4091.93458626603
      Z: -16258.9236962179
      VX: 1.49641430481871
      VY: -1.03625797448493
      VZ: 0.0014375710307264

      Hit apply and change the state type to Keplerian. There is an error in the SMA. The expected SMA = 42095
      But the value GMAT outputs SMA = 42095.00001108487.
      This leaves an error of 0.00001108487 which is outside the error tolerance of 1e-5.

      Then change the state type to Modified Keplerian. There is an error in RadApo. The expected RadApo = 76536.3628709998
      But the value GMAT outputs RadApo = 76536.3628869933
      This leave an error of 0.000015993500710465014 which is outside the error tolerance of 1e-5.

      Finally change the state type to Equinoctial. There is an error in the SMA that is the same as the Keplerian state type error.
