  Magnetic flux ropes with helical field lines and strong core field are
ubiquitous structures in space plasmas. Recently, kinetic-scale flux ropes have
been identified by high-resolution observations from Magnetospheric Multiscale
(MMS) spacecraft in the magnetosheath, which have drawn a lot of attention
because of their non-ideal behavior and internal structures. Detailed
investigation of flux rope structure and dynamics requires development of
realistic kinetic models. In this paper, we generalize an equilibrium model to
reconstruct a kinetic-scale flux rope previously reported via MMS observations.
The key features in the magnetic field and electron pitch-angle distribution
measurements of all four satellites are simultaneously reproduced in this
reconstruction. Besides validating the model, our results also indicate that
the anisotropic features previously attributed to asymmetric magnetic
topologies in the magnetosheath can be alternatively explained by the
spacecraft motion in the flux rope rest frame.
