Abstract:
Results are presented of Stromgren uvby(beta) photometry for 213 stars
earlier than G0 and brigher than mpg of about 10.7mag 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), m1,
c1, 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.
