  The rare inclusive decay $\bar{B}\rightarrow X_s\gamma$ is an important probe
of physics beyond the standard model. The largest uncertainty on the decay rate
and CP asymmetry comes from operators that appear at order $1/m_b$ in the heavy
quark expansion. One of the three leading contributions in the heavy quark
expansion, $Q_1^q-Q_{7\gamma}$ is described by a non-local function whose
moments are related to HQET parameters. We use recent progress in our knowledge
of these parameters to better constrain their contributions to the total rate
and CP asymmetry.
