SED of the Crab Nebula obtained by processing data with non-standard wobble offsets that has also been used by Aleksić et al. (2016b). The solid error bars indicate statistical errors, while the lighter coloured, wider error bars were obtained by also propagating the uncertainties from the constructed exposure model. Because of the short observation times of the data sets, the uncertainties of the fitted exposure map can be larger than the statistical error of the data points.
