The SEDs for the constant B-field and MHD flow model. The data compilation is based upon Aharonian et al. (2004) with updates listed in Table 1 and modifications (e.g. scaling of the SPI flux) described in the text. See Sect. 2 for further details. The synchrotron emission fitted to the data is shown by the blue solid line while the remaining components (low energy part and inverse Compton emission) naturally result from the model. Therefore, blue data points have been included in the fit whereas the gray points have been excluded. In addition to the nonthermal continuum emission, the contribution of dust and line emission from the filaments is indicated with a magenta dashed line. The lower panels show the residuals of the fit.
