  • CCD photometry of the distant southern globular cluster NGC 5824 
    Cannon, R. D; Sagar, R; Hawkins, M. R. S (Royal Astronomical Society, 1990-03)
    A V, (B-V) C-M diagram for the distant globular cluster NGC 5824 is obtained from CCD observations of 285 stars reaching V = 20.5. Assuming a reddening of E(B-V) = 0.13, the color of the giant branch at the level of the ...
  • The giant branch of the Fornax dwarf spheroidal galaxy 
    Sagar, R; Hawkins, M. R. S; Cannon, R. D (The Royal Astronomical Society, 1990-01)
    A color-magnitude diagram for a large sample of stars in the Fornax dwarf spheroidal galaxy has been obtained from BV electronographic observations. These reach to the level of the horizontal branch, below V = 21 mag. The ...
  • Photoelectric and electronographic photometry of the globular cluster NGC 1851 
    Sagar, R; Cannon, R. D; Hawkins, M. R. S (Royal Astronomical Society, 1988-05)
    The colour-magnitude diagram for NGC 1851 is presented to a limit of V = 21.0 mag, approximately 2 mag below the main-sequence turn-off point, on the basis of UBV photoelectric photometry and electronographic BV photometry. ...
