Spectral properties of a sample of type 1 AGNs: influence of star
  formation
  To find the spectral properties of AGNs in optical spectral band (around the
Hb line) we constructed an Fe II template, that is covering Fe II emission from
4100 A to 5600 A. Using the new Fe II template we explored spectral properties
of 302 type 1 AGNs. The most interesting results we found is the correlation of
the Hb Full Width at Half Maximum (FWHM) and luminosity for a subsample of type
1 AGNs where the ratio of narrow lines indicates a significant starburst
contribution.
