EXOSAT measurement of the spectrum of Markarian 382.
Abstract
The 0.1-10 keV X-ray spectrum of a Seyfert galaxy known as Markarian 382 (Mkn 382) is presented based on observations with the EXOSAT. The energy index (α) for the power-law X-ray continuum of Mkn 382 is measured to be 1.2^+0.16^_0.14_ which is higher than the canonical value found for the Seyfert galaxies. There is no evidence for intrinsic absorption, soft excess or any line feature in the source. The X-ray emission was found to be steady during the observations. The 2-10 keV X-ray luminosity of Mkn 382 is 2.3 10^43^ erg s^-1^.
