  • Further observations of Hipparcos red stars and standards for UBV(RI)C photometry 

    Kilkenny, David; Koen, Chris; van Wyk, F.; Marang, F.; Cooper, D. (Oxford University Press, 2007)
    We present homogeneous and standardized UBV(RI)C JHK photometry for over 100 M stars selected from an earlier paper on the basis of apparent photometric constancy. L photometry has been obtained for stars brighter than ...
  • Improved SAAO–2MASS photometry transformations 

    Koen, Chris; Marang, F.; Kilkenny, David; Jacobs, C. (Oxford University Press, 2007)
    Near-infrared photometry of 599 stars is used to calculate transformations from the South African Astronomical Observatory (SAAO) JHK system to the Two-Micron All-Sky Survey (2MASS) JHKS system. Both several-term formal ...
  • UBV(RI)C JHK observations of Hipparcos-selected nearby stars 

    Koen, Chris; Kilkenny, David; van Wyk, F.; Marang, F. (Oxford University Press, 2010)
    We present homogeneous, standardized UBV(RI)C photometry for over 700 nearby stars selected on the basis of Hipparcos parallaxes. Additionally, we list JHK photometry for about half of these stars, as well as L photometry ...
