MECS Image of CAS A

The young supernova remnant CAS-A has been observed with the Beppo SAX NFI on August 6 1996. The image on the left shows the smoothed MECS2 1.5-10 keV intensity image of CAS A (detector coordinates). The size of the image is 20 x 20 arcmin. The image on the right shows a smoothed softness ratio obtained by divinding two images accumulated in narrow bands centred on the Si 1.8 keV and Fe 6.6 emission lines. Note the considerable amount of structure recognizable down to a scale of about 2 arcmin.
