    • Chandra/ACIS subpixel event repositioning. II. Further refinements and comparison between backside and front-side illuminated X-ray CCDs 

      Li, Jingqiang; Kastner, Joel; Prigozhin, Gregory; Schulz, Norbert; Feigelson, Eric; Getman, Konstantin (Astrophysical Journal, 2004-08-01)
      We further investigate subpixel event repositioning (SER) algorithms in application to Chandra X-ray Observatory (CXO) CCD imaging. SER algorithms have been applied to backside illuminated (BI) Advanced CCD Imaging ...
    • Refining Chandra/ACIS subpixel event repositioning using a backside illuminated CCD model 

      Li, Jingqiang; Kastner, Joel; Prigozhin, Gregory; Schulz, Norbert (Astrophysical Journal, 2003-06-10)
      Subpixel event repositioning (SER) techniques have been demonstrated to significantly improve the already unprecedented spatial resolution of Chandra X-ray imaging with the Advanced CCD Imaging Spectrometer (ACIS). Chandra ...
    • 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, ...
