PHOTOELECTRIC UBVRI SEQUENCES IN THE MAGELLANIC CLOUD CLUSTERS NGC-458, NGC-1783, AND NGC-1841

We present UBVRI photoelectric sequences for the Small Magellanic Clou d cluster NGC 458 and the Large Magellanic Cloud clusters, NGC 1783 an d NGC 1841. All of them fall in fields suitable for CCD coverage. The number of stars and the range of magnitude and colors are NGC 458, 15 stars with 11.6<V<15.9, 0.0<B- V<1.2; NGC 1783, 10 stars with 13.1<V<1 5.9, -0.2<8- V<1.0; NGC 1841, 9 stars with 14.3<V<15.7, 0.6<B - V<1.2. The stars were measured an average of six times on at least three dif ferent nights. Four stars are in common with previous works in NGC 458 and four in NGC 1783.
