Copernicus: The Spatial Distribution of the X-ray Emission from IC443
Abstract
The MSSL X-ray instrumentation on the Copernicus satellite has observed the spatial structure of the supernova remnant IC 443. The soft (0.5-1.4 keV) X-ray emission is found to be strongly correlated with the bright optical filaments in the northeast. The total intensity is consistent with previous observations of the remnant. An upper limit of 4 by 10 to the -11th power erg/sq cm/sec can also be assigned to the flux in the 0.5-1.4-keV band from the nearby pulsar PSR 0611 + 22.
