| DIRECT | (DIRECT survey) |
| Write: | <<DIRECT VNNNNN M31A>> <<DIRECT VNNNNN M33A>> |
| Object: | V* (SIMBAD class: Variable* = Variable Star) |
| Note: | DIRECT project, to obtain the direct distances to M 31 and M 33, using detached eclipsing binaries and Cepheids. After discussion with authors: Format 'VNNNNN DNNA', letter 'D' for DIRECT project, not used in SIMBAD. Format 'VNNNNN MNNA', in SIMBAD: letter 'V' for variable, 'NNNNN' for the number of the star in the database, followed by the name of the field: M31A, M31B, M31C, M31D, M31F. |
| in source: | M 31 = NGC 224 |
