    • A large, uniform sample of X-ray emitting AGN from the ROSAT All-Sky and Sloan Digital Sky Surveys: the Data Release 5 Sample 

      Anderson, Scott; Margon, Bruce; Voges, Wolfgang; Plotkin, Richard; Syphers, David; Haggard, Daryl; Collinge, Matthew; Meyer, Jillian; Strauss, Michael; Agueros, Marcel; Hall, Patrick; Homer, Lee; Richards, Gordon; Richmond, Michael; Schneider, Donald; Stinson, Gregory; Vanden Berk, Daniel; York, Donald (American Astronomical Society - The Astronomical Journal, 2003-11)
      We describe further results of a program aimed to yield ∼104 fully characterized optical identifications of ROSAT X-ray sources. Our program employs X-ray data from the ROSAT All-Sky Survey (RASS), and both optical imaging ...

      Anderson, Scott; Voges, Wolfgang; Margon, Bruce; Trumper, Joachim; Agueros, Marcel; Boller, Thomas; Collinge, Matthew; Homer, Lee; Stinson, Gregory; Strauss, Michael; Annis, James; Gomez, Percy; Hall, Patrick; Nichol, Robert; Richards, Gordon; Schneider, Donald; Vanden Berk, Daniel; Fan, Xiaohui; Ivezic, Zeljko; Munn, Jeffrey; Newberg, Heidi Jo; Richmond, Michael; Weinberg, David; Yanny, Brian; Bahcall, Neta; Brinkmann, Jonathan; Fukugita, Masataka; York, Donald (American Astronomical Society - The Astronomical Journal, 2003-11)
      Many open questions in X-ray astronomy are limited by the relatively small number of objects in uniform optically-identified and observed samples, especially when rare subclasses are considered, or when subsets are ...
    • The Sloan Digital Sky Survey Monitor Telescope Pipeline 

      Tucker, Douglas; Kent, Stephen; Richmond, Michael; Annis, James; Smith, James; Allam, S.; Rodgers, C.; Stute, J.; Adelman-McCarthy, Jennifer; Brinkman, Jonathan; Doi, Mamoru; Finkbeiner, Douglas; Fukugita, Masataka; Goldston, J.; Greenway, B.; Gunn, James; Hendry, John; Hogg, David; Ichikawa, Shin-ichi; Ivezic, Zeljko; Knapp, Gillian; Lampeitl, Hubert; Lee, Brian; Lin, Huan; McKay, Timothy; Merrelli, A.; Munn, Jeffrey; Neilsen, E.; Newberg, H.; Richards, Gordon; Schlegel, David; Stoughton, Christopher; Uomoto, Alan; Yanny, Brian (Wiley InterScience: Astronomische Nachrichten, 2006-11)
      The photometric calibration of the Sloan Digital Sky Survey (SDSS) is a multi-step process which involves data from three different telescopes: the 1.0-m telescope at the US Naval Observatory (USNO), Flagstaff Station, ...
