We present a calculation of the intermediate window quantity of the
hadronic vacuum polarization contribution to the muon g-2 using a
Lorentz-covariant coordinate-space method at a fixed pion mass of ~350
MeV. This method is more flexible in the choice of the integration
kernel than the time-momentum representation and gives a different
perspective on the systematic errors of the g-2 calculation. It
furthermore serves as a check for the recent results of the Mainz
group.
