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.
