Fitting LINER nuclei within the active galactic nucleus family: a matter of obscuration? Gonzalez-Martin O., Masegosa J., Marquez I., Guainazzi M. <Astrophys. J., 704, 1570-1585 (2009)> =2009ApJ...704.1570G

They show column densities at soft energies (0.5-2keV) mostly related to the diffuse emission around the active galactic nucleus (AGN), showing a correlation with the optical extinction. Column densities at hard energies (2-10keV) seem to be much higher than what would be expected from the optical extinction. They might be associated with the inner regions of the AGN, buried at optical wavelengths. Description: Our sample is presented in Gonzalez-Martin et al., 2009A&A...506.1107G, where all the observational details are exhaustively explained. The sample was extracted from the multi-wavelength LINER catalog compiled by Carrillo et al. (1999RMxAA..35..187C; hereinafter MCL). The sample includes all the galaxies in MCL with available Chandra data up to 2007 June 30 and XMM-Newton data up to 2007 April 30. It includes 108 LINERs with Chandra data and 107 LINERs with XMM-Newton data. Seventy-six objects are present in both archives yielding to a total of 139 LINERs. File Summary:
