Abstract:
This investigation presents a photometric study of the Galactic
structure toward the Carina arm tangent. The field is located between
280° and 286° Galactic longitude and -4° to 4°
Galactic latitude. All currently available uvbyβ data are used to
obtain homogeneous color excesses and distances for more than 260
stars of spectral types O to G. We present revised distances and
average extinction for the open clusters and cluster candidates
NGC 3293, NGC 3114, Loden 46, and Loden 112.
