  1. Australian Government Geoscience Australia Informal presentation on the optical spectroscopic program Oleg Titov UTAS, Hobart, 5 June 2012 03/000

  2. Telescopes • BTA, 6-meter (Russia) • NTT, 3.58-meter (Chile) • Gemini South, 8.1-meter (Chile) • Gemini North, 8.1-meter (Hawaii) • NOT, 2.5-meter (La Palma)

  3. Quasars • Presumably, the radio sources observed with VLBI • Radio strong quasars with large dropouts (g-r), (r-i), etc • SuperCOSMOS, SDSS • VLBI catalogues, FIRST, MASIV

  4. Red shifts • 5 reshifts at BTA (2008-2010) • 30 redshifts at NTT (August, 2010) • 120+ redshifts at all 5 scopes in 2011-2012 • Visitor Mode (BTA, August, 2011; NTT, December, 2011; NOT, May, 2012) • Service Mode (Gemini North, South)

  5. Red shifts • 0<z<1, 37 • 1<z<2, 52 • 2<z<3, 24 • 3<z<4, 4 • Before the last run at NOT in May, 2012
