Data from Fan X., et al. 1996, Astron. J. 112, 628
- Cross-reference table: column 12 added,
- BATC spectrophotometry,
- Additional rectangular positions.
A new kind of datatype has been introduced in the database: batc, which stands
for the nine-colour CCD spectrophotometry developed by the Beijing-Arizona-Taipei-Connecticut
(BATC) collaboration.
The cross-references provided in the published catalogue (only with Sanders) have been
extended to the stars of Montgomery et al. and of Racine. So far, cross-references
for 938 stars have been determined and the corresponding data have been included in the
database. This work will be continued to match as many stars as possible.
1999 August 24
Data from Abt H.A., Willmarth D.W. 1999, Astrophys. J. 521, 682
- Individual radial velocities,
- Mean radial velocities,
- Rotational velocities,
- Orbital elements,
- Duplicity remarks.
Data from Abt H.A., Willmarth D.W. 1999, Astrophys. J. 521, 682
- Individual radial velocities,
- Mean radial velocities,
- Rotational velocities,
- Orbital elements,
- Duplicity remarks.
1999 August 17
Data from Kharchenko N., et al. 1997, Astron. Nachr. 318, 253
- New cross-reference table,
- UBV photographic photometry,
- Membership probabilities,
- Coordinates,
- New XY rectangular positions.
A new numbering system has been adopted for IC 2157. The 2005 stars of
Kharchenko N., et al. have been numbered sequentially, because their
original numbers go from 216992 to 256218. In column R1 of the cross-reference
table, the first digit (2) has been omitted.
The membership probabilities stored in the database are the maximum of
the core and corona probabilities, given separately by Kharchenko et al.
