Default What's the difference between the JointReactionMoment and the NetMoment?

For instance,
Output.BodyModel.Left.Leg.MomentMeasure.AnkleJoint ReactionMoments
Output.BodyModel.Right.Leg.MomentMeasure.AnklePlan tarFlexionNetMoment

What's more, there are JointReactionMoment and the NetMoment for the Ankle joints and Knee Joints in the output,
however, why only the NetMoment for the Hip joint can be found ? Is anything unique for the Hip joint?

The joint reaction forces are reaction forces from the joints... so eg. 3 force reaction from a spherical joint, for a revolute joint 3 forces and 2 moments.

The netmoment values are different this is the moment supplied by the muscles... so three moments in hip and one in the knee.
