ADC_Keywords: Active gal. nuclei ; Photometry, UBVRI ; Redshifts Keywords: galaxies: active - galaxies: Seyfert - galaxies: nuclei Abstract: We use one of the deepest spectroscopic samples of broad-line active galactic nuclei (AGN) currently available, extracted from the VIMOS VLT Deep Survey (VVDS, Cat. III/250), to compute the MgII and CIV virial-mass estimates of 120 super-massive black holes in the redshift range 1.0<z<1.9 and 2.6<z<4.3. File Summary:

Note (2): Flag 14 AGN have a 100% secure redshift based on at least two emission lines. Flag 13 AGN have a redshift which is based on one broad emission line with a confident identification: either no other identification is very similar given our spectral wavelength coverage, or some faint additional features are supporting the chosen redshift Note (5): We indicate here, AGN for which a single broad emission line is detected in the VVDS original spectrum but for which a second line is detected at shorter wavelength either in our VIMOS and FORS follow-up programs, or in one of these spectroscopic survey: 2Qz = 2Qz, Croom et al., 2004, Cat.

Note (2): Note on redshift as follows: a = from Hα b = from MgII c = from CIII d = from CIV
Global notes: Note (G1): Reg is coded as follows: A = CDFS: Deep mode B = 0226-04: Deep mode C = 1003+01: Wide mode D = 1400+05: Wide mode E = 2217+00: Wide mode Note (G3): Photometry in the CDFS field is extracted from the EIS catalog (Arnouts et al., 2001, Cat. J/A+A/379/740) while in the 4 other fields it corresponds to the VVDS imaging survey (McCracken et al., 2003A&A...410...17M, Cat. II/286). These magnitudes are corrected for galactic extinction using the dust map provided by Schlegel et al. (1998ApJ...500..525S) Note (G4): Based on the half-light radius of the object. Object with with IAB>22.5 or in the CDFS and VVDS-1400+05 field are not classified.
