  In the microquasar V4641 Sgr the spin of the black hole is thought to be
misaligned with the binary orbital axis. The accretion disc aligns with the
black hole spin by the Lense-Thirring effect near to the black hole and further
out becomes aligned with the binary orbital axis. The inclination of the radio
jets and the Fe$K\alpha$ line profile have both been used to determine the
inclination of the inner accretion disc but the measurements are inconsistent.
Using a steady state analytical warped disc model for V4641 Sgr we find that
the inner disc region is flat and aligned with the black hole up to about $900
R_{\rm g}$. Thus if both the radio jet and fluorescent emission originates in
the same inner region then the measurements of the inner disc inclination
should be the same.
