M. F. ; Venkatesan, D. ; Garmire, G. Abstract The low-energy X-ray spectrum (0.15-3.0 keV) and X-ray centroid position of the supernova remnant IC 443 have been determined using data obtained by the HEAO-1 A-2 experiment. The spectrum exhibits a low-energy excess over and above that predicted by an extrapolation of the higher-energy spectrum determined by Parkes et al (1976). The excess can be attributed to line emission, predominately from high-ionization states of iron from a plasma at a temperature of 7.7 + or - 0.6 or -4.3 x 10 to the 6th K. Other models which fit the data are discussed, in particular, a lower-temperature component required to explain the Fe X optical emission.
