Abstract: A large fraction of Seyfert 1-1.5s exhibit an excess of X-ray emission, known as soft excess, below 2Kev. This soft excess provides a useful diagnostic tool to understand the accretion flow mechanism around the active galactic nuclei. In the present work we have conducted a systematic analysis of a XMM newton observation of a Seyfert galaxy as observed by the satellite in November 2016. The object was earlier observed by Chandra, ASCA, ROSAT and RXTE. These previous observations suggest a relatively flat spectrum in the low-energy side of the spectrum. The XMM-Newton observation however suggest clear evidence of presence of soft-excess. So we conducted a detailed spectral analysis of the soft excess using different available models and found that the emission can be equally well explained with the help of the warm corona model and the relativistic reflection models.
