Abstract:
    Results are presented of Stromgren uvby(beta) photometry for 213 stars
    earlier than G0 and brigher than m sub pg of about 10.7 m in Selected
    Area 203. The observed area lies close to the geometric center of the
    Chamaeleon-Musca dark clouds complex. The results yield V, (b-y), m sub 1,
    c sub 1, and beta on the standard systems, with overall rms errors for one
    observation of one star of 0.010, 0.004, 0.007, 0.009, and 0.011,
    respectively.
