cds-question@unistra.frsupernova-remnantsx-ray-sourceschemical-abundancesWe have performed the first detailed spatially resolved spectroscopy of Cas A in the 1.6-10keV energy range, using data taken with the Medium Energy Concentrator Spectrometer (MECS) on board the BeppoSAX Observatory. The well calibrated point spread function in the central region of the MECS allowed us to perform a spatial deconvolution of the data at full energy resolution. We eventually generated a set of spectra, covering a region of ~3' radius around the centre of Cas A. The data used were obtained on Aug 1996, Sep 1996 and Nov 1997.2001A&A...368..267Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/368/267CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/441/307 : Proper motions and brightness of Cas A (Anderson+ 1995)J/ApJ/456/234 : Cas A radio knots spectral indices (Anderson+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/368/267https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/368/267http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/368/267https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/368/267https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/368/267http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/368/267GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-raydefaultJ/A+A/368/267/table4Results obtained fitting the 182 spectra with a non-equilibrium ionisation plasma modelrecnoRecord number assigned by the VizieR team.
