Many stars in the field of Ruprecht 55 appear in SIMBAD without coordinates. A complete list of stars in both main studies of the field is given below. All the positions come from UCAC1 or 2MASS. This complements the list of OB stars in the field sent previously. Some photoelectric photometry of the Dodd-Ellery stars appears in a paper by Ana Orsatti (1995AJ....110.1728O), but which shows only dereddened V and U-B. ------------------------------------------------------------------------------- Coordinates and identifications for stars in Ruprecht 55 version: 7 May 2003 sources: 1975A&AS...20...85M MOFFAT A.F.J. and VOGT N.
