 \caption{Best-fit values for the available observations 
 during the pre-outburst flare, where the CRSF energy is 
 measured at a higher position, for the sum of the observations 
 during the flare, and for one observation close to the maximum
 of the main outburst. $L$ is the luminosity in 
 units of $10^{37}~\ergs$ in the $5{-}50~\kev$ range.
 Errors are $90\%$ confidence for one parameter of interest
 ($\chi^{2}_{\min}+2.7$).}\label{tab:spike_obs}
