Abstract:
Four-colour and H{beta} photometry is introduced for 594 stars earlier than
G0 in the Kapteyn's Selected Area 194. The results give V, b-y, m_1_, c_1_,
and {beta} on the standard systems, with overall rms errors for one
observation of one star of 0.009mag, 0.004mag, 0.006mag, 0.009mag, and
0.009mag, respectively. The data cover an area of about 5deg x 5deg and is
intended for an investigation of the distribution of the interstellar
medium toward the northern part of the Southern Coalsack and its
surroundings. A comparison to earlier results obtained by other authors has
shown that the c_1_ indices obtained for the late type stars were
underestimated, in average, by 0.020mag. Since such difference may account
for an error of little more than 10% in the estimated stellar distances, a
correction was applied to the c_1_ index of these stars.
