All include fields suitable for CCD coverage. The number of stars and the range of magnitudes and colors are: * NGC 5286: 8 stars 13.6<V<15.3, 0.6<B-V<1.3 (table2) * NGC 5927: 11 stars 11.3<V<14.9, 0.3<B-V<1.6 (table3) * NGC 6541: 16 stars 12.2<V<15.7, 0.2<B-V<1.6 (table4) The stars were measured an average of seven times on at least five different nights. To the best of our knowledge, none of these stars have UBVRI photoelectric measurements reported by other authors. Description: The observations were made during 11 excellent photometric nights in 1994, using the 1m Yale telescope at CTIO (March, June-July), and the 1m telescope at ESO-La Silla (August). The identification and accurate positions of the stars studied in this paper was achieved by B. Skiff (Lowell Obs.) in October 2010 File Summary:
