Abstract:
The results concerning photoelectrically observed UBV magnitudes and
colors of bright to intermediately faint stars near three globular
clusters (NGC 2808, 5927, and 6101) are assembled.
Description:
The observations were obtrained in May 1969, at the CTIO (Cerro Tololo
Inter-American Observatory) 36-inch reflector; the 60-inch reflector
was used got some of the fainter stars in NGC 5927.
The identification and accurate positions of the stars studied in this
paper was achieved by B. Skiff (Lowell Obs.) in October 2010
