ordering of Jacobian

I don't find it anywhere explicitly in the documentation what the ordering
of the six rows of Jacobians are in KDL. The most reasonable guess is
translation_x, _y, _z and rotation_x, _y, _z, but can someone confirm this?

The Twist class uses this ordering for its definition of the [] operator:

That is indeed correct, I indeed noticed that we do not have explicit
documentation on this. For the twist more information can be found on
