spex_summ_fit_done
spex_summ_fit_done is a mask showing which fit time intervals have been fit. The array is dimensioned by the number of fit time intervals. For each interval, the mask has a value of 0 or 1 indicating whether a fit was done for the time interval (1 means yes).Look at this parameter, as well as the spex_summ_fit_emask, to determine which energy/time bins are valid for fit results:
qenergy = where (s.spex_summ_emask) - indices of energy bins used
qtime = where (s.spex_summ_fit_done) - indices of time intervals fit
