  We present a class of one-dimensional, strictly neutral, Vlasov-Maxwell
equilibrium distribution functions for force-free current sheets, with magnetic
fields defined in terms of Jacobian elliptic functions, extending the results
of Abraham-Shrauner (Phys. Plasmas 20, 102117, 2013) to allow for non-uniform
density and temperature profiles. To achieve this, we use an approach
previously applied to the force-free Harris sheet by Kolotkov et al. (Phys.
Plasmas 22, 112902, 2015). In one limit of the parameters, we recover the model
of Kolotkov et al., while another limit gives a linear force-free field. We
discuss conditions on the parameters such that the distribution functions are
always positive, and give expressions for the pressure, density, temperature
and bulk-flow velocities of the equilibrium, discussing differences from
previous models. We also present some illustrative plots of the distribution
function in velocity space.
