J/A+AS/140/351 UBV photometry of SGP AGNs (La Franca+, 1999) ================================================================================ A survey of UV-excess AGNs in the South Galactic Pole La Franca F., Lissandrini C., Cristiani S., Miller L., Hawkins M.R.S., McGillivray H.T. =1999A&AS..140..351L ================================================================================ ADC_Keywords: QSOs ; Active gal. nuclei ; Photometry, UBV ; Redshifts Keywords: cosmology - catalogs - surveys - quasar: general Abstract: Spectra, position, magnitudes and colors are presented for 485 faint (B_J_<20.5) emission line objects selected with the ultraviolet-excess (UVX) criterion on a area of 24.6 sq. deg. in the South Galactic Pole. The objects were selected from the analysis of pixel-to-pixel stacking of COSMOS scans of UKST U_J_ and R plates. The candidates were observed with the Meudon-ESO Fiber Optics System (MEFOS) at the ESO 3.6m telescope. 429 type 1 AGNs have been identified (373 in the redshift range 0.3=2.2 (Warren+ 1991) VII/179 : Kiso Survey for ultraviolet-excess galaxies.
