Accretion rate in AGN and X-ray-to-optical flux ratio at z $\le$ 0.2
  We explored a sample of 545 local galaxies using data from the 3XMM-DR7 and
SDSS-DR8 surveys. We carried out all analyses up to z\,$\sim$\,0.2, and we
studied the relation between X/O flux ratio and accretion rate for different
classes of active galaxies such as LINERs and Seyfert 2. We obtained a slight
correlation between the two parameters if the whole sample of AGN is used.
However, LINERs and Sy2 galaxies show different properties, slight correlation
and slight anti-correlation, respectively. This could confirm that LINERs and
Sy2 galaxies have different accretion efficiencies and maybe different
accretion disc properties,as has been suggested previously.
