Abstract:
    Photometric UBVIc data are presented for the open clusters NGC2439,
    NGC2489, NGC2567, NGC2627, NGC2658, and NGC2910. From a combination of
    the new BVIc technique and the analysis of the CMDs, the color excess
    E(B-V), the distance modulus, and approximate age are given for these
    clusters and NGC2421.


ERRATUM NOTE: in the publication the table headings are in error.
    The captions of the tables are:
    Table 7 = NGC 2421  NOT 2439
          8 =     2439      2489
          9 =     2489      2567
         10 =     2567      2627
         11 =     2627      2658
         12 =     2658      2910
          and NGC 2910 was not published as a table, but is present here.
