J/A+AS/128/131      UBV photometry of NGC 2323  (Claria+ 1998)

Photometric study of the open cluster NGC 2323 Claria J.J., Piatti A.E., Lapasset E. <Astron. Astrophys. Suppl. Ser. 128, 131 (1998)> =1998A&AS..128..131C (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, open ; Photometry, UBV ; Cross identifications Keywords: open clusters: individual: NGC 2323 - open clusters: general - HR diagram 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. File Summary:

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.
