  We analyze the broad-band X-ray spectrum (0.3-50 keV) of the luminous Seyfert
1 / quasar PG 1211+143 - the archetypal source for high-velocity X-ray outflows
- using near-simultaneous XMM-Newton and NuSTAR observations. We compare pure
relativistic reflection models with a model including the strong imprint of
photoionized emission and absorption from a high-velocity wind (Pounds16a,16b),
finding a spectral fit that extrapolates well over the higher photon energies
covered by NuSTAR. Inclusion of the high S/N XMM-Newton spectrum provides much
tighter constraints on the model parameters, with a much harder photon index /
lower reflection fraction compared to that from the NuSTAR data alone. We show
that pure relativistic reflection models are not able to account for the
spectral complexity of PG 1211+143 and that wind absorption models are strongly
required to match the data in both the soft X-ray and Fe K spectral regions. In
confirming the significance of previously reported ionized absorption features,
the new analysis provides a further demonstration of the power of combining the
high throughput and resolution of long-look XMM-Newton observations with the
unprecedented spectral coverage of NuSTAR.
