(99.7 per cent) of the Gaussian flux at 3.55keV in counts $\rm{cm^{-2}~s^{-1}}$. The annotations show the best-fit value and the confidence interval obtained using MCMC. Residuals are shown for the fit with upper (blue) and lower (red) confidence limit of the 3.55keV Gaussian flux. For the effective-area curve see Fig. \[fig:fakelinemerge\].[]{data-label="fig:acissres"}](merge_limit_s_unabs_385_470.pdf){width="48.00000%"}
