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 Kα 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/LEdd ratios, which are probably related to Boroson & Green eigenvector~1.
