Broadband X-ray spectrum of IGR J18450-0435 obtained by summing the data from the three XMM-Newton EPIC cameras in observation 0306170401, combining the data from the two RGSs in the same observation, and using the INTEGRAL data described in the text. The best fit is obtained with a partial covering model comprising a cutoff power law and an iron line. The middle panel shows the residuals from this fit. The bottom panel shows the residuals obtained by fitting the spectrum with the model proposed by Zurita Heras & Walter (2009).
