\caption{\label{table:fit_pre_post}To search for spectral variability, all datasets were fit with a simple model (const*wabs*(cutoff+diskbb)). The normalization of the thermal and non-thermal components are listed below. $kT_{\rm in}=0.25$~keV, $\Gamma=0.42$, and $E_{C}=14$~keV, $C_{{\rm MOS1}}=0.89$, and $C_{{\rm MOS1}}=0.88$ are fixed.}
