GINGA Observations of SN 1006 and the Lupus Region

X-rays from SN 1006 and the adjacent Lupus region were observed with Ginga. We found extended emission from the Lupus region, which could be described equally well by either a thermal bremsstrahlung model with kT = 7--10 keV or a power-law model with photon index of 2. An Fe line at an energy of about 6.2--6.4 keV with an equivalent width of 0.1--0.4 eV was also found. After subtracting this local background, the spectrum of SN 1006 was well fitted with a single power-law with index 3.2--3.3. The equivalent width of Fe K-emission line from SN 1006 is less than 120 eV (at the 90% confidence level).
