Scientific paper

An imaging spectrophotometric observation of the galactic supernova remnant (SNR) SN1006 in the soft X-ray band (0.1 to 1.4 keV) was carried out. The experiment used the Columbia Imaging Gas Scintillation Proportional Counter (IGSPC) at the focal plane of a rocketborne X-ray telescope. SN1006 was the subject of much interest, both theoretical and observational, in recent years but its basic nature has remained quite controversial. It was felt that such an object would be an ideal target by which to prove the advantages of the IGSPC for use in X-ray astronomy. The integrated height spectrum is analyzed in terms of recent nonequilibrium ionization (NEI) thermal emission codes, which are expected on first principles to give a more accurate description of the emission than earlier equilibrium models. Parameters characterizing the SNR and the surrounding interstellar medium are then derived under the simplifying assumption of spatial homogeneity.
