Scientific paper
The central engine of the the Narrow Line Seyfert 1 galaxies is being probed. We use the ASCA and RXTE data to model the X-ray primary continuum as well as the reflected component and iron $K\alpha$ line. Since these are strongly coupled, we obtain independent measurements of the disc ionization level and the orientation dependent reflection amplitude. Using the available Optical/UV data we also estimate the black hole masses and the $L/L_{Edd}$ ratios, which are probably related to Boroson & Green eigenvector~1.
