The left picture shows the deconvolved photon spectra of the black hole/neutron star X-ray transient XTE J0421+560 during two BeppoSAX TOO observations. The model includes two bremsstrahlung components plus emission lines of O, Ne/Fe-L, Si, S, Ca and Fe-K. The bottom part shows the data to model ratios. The X-ray images in different energy bands shown on the right side have been collected with the LECS instrument. Courtesy of A. Parmar, Space Science Department of ESA and F.
