X-ray structure of the Cygnus Loop.
X-ray emission from the Cygnus Loop was observed in the energy region around 0.2 to 1 keV with a collector that focused X-rays along one dimension while scanning across the nebula. The total integrated intensity is 13 nanoerg per square centimeter per second. The one-dimensional X-ray structure has the same angular size - about 3 degrees - as the outermost boundaries of the optical filaments. There is no increase in X-ray emission at the center of the nebula nor at the strong feature that is seen in certain radio maps. The X-ray spectrum is consistent with thermal radiation from a hot plasma at a temperature of about 4 million K.
