  We present here a minor modification of our numerical implementation of the
Hall effect for the 2D Riemann solver used in Constrained Transport schemes, as
described in Marchand et al. (2018). In the previous work, the tests showed
that the angular momentum was not conserved during protostellar collapse
simulations, with significant impact. By removing the whistler waves speed from
the characteristic speeds of non-magnetic variables in the 1D Riemann solver,
we are able to improve the angular momentum conservation in our test-case by
one order of magnitude, while keeping the second-order numerical convergence of
the scheme. We also reproduce the simulations of Tsukamoto et al. (2015) with
consistent resistivities, the three non-ideal MHD effects and initial rotation,
and agree with their results. In this case, the violation of angular momentum
conservation is negligible in regard to the total angular momentum and the
angular momentum of the disk.
