Description:
UBV and DDO photoelectric photometry in the field of the open cluster
NGC 2323 is presented. The analysis yields 109 probable members; one
of them being a red giant, and 3 possible members. The basic cluster
parameters are derived. NGC 2323 appears not to be physically
connected to the CMa OB1 association.

Note (1): The last columns are not in the original publication,
but were supplied by B. Skiff ().
Positions are generally originated from GSC (Cat. I/220),
unless stated in the "Rem" column ("A1" stands for Monnet's
"USNO-A1.0 Catalogue", see Cat. I/243).
GSC names are supplied, and names in some other catalogues are
supplied in the Rem column.
