The data we collected will be used to evaluate the line-to-continuum time lag in an attempt to test the idea that the accretion rate in NLS1s is larger than in other Seyfert 1 galaxies.Poster contribution presented at the Joint MPE,AIP,ESO workshop on NLS1s, Bad Honnef, Dec. 1999, to appear in New Astronomy Reviews; also available at http://wave.xray.mpe.mpg.de/conferences/nls1-workshopAstrophysicstext
