New Data added in the Database in October 1998
This page informs on the progress made in the inclusion of new data in the database.
Data added previously in 1998: September |
August | July | June | May
1998 October 28
Data from Montgomery K.A., et al. 1994, AJ 108, 585
- New cross-reference table,
- UBV CCD data,
- VIc CCD data,
- New rectangular X,Y positions.
The numbering system defined by the catalogue of Montgomery et al.
(8062 stars) has been adopted for NGC 6791 in place of the numbering
of Kinman previously used.
The various data sets of Kaluzny and collaborators (1990, 1992, 1995),
which represent several thousand stars, have to be installed.
1998 October 27
Data from Kassis M., et al. 1997, AJ 113, 1723
- New cross-reference table,
- VIc CCD data,
- New rectangular X,Y positions.
The numbering system defined by the catalogue of VI photometry of Kassis et al.
(3727 stars ) has been adopted for Mel 66 in place of the numbering
of Hawarden used previously.
Data from Orr A. 1994, Diploma work (Geneva Univ.)
- Cross-reference table: column 5 added,
- UB electronographic data,
- Additional rectangular X,Y positions.
1998 October 26
Data from Kassis M., et al. 1997, AJ 113, 1723
- New cross-reference table,
- UBV CCD data,
- VIc CCD data,
- New rectangular X,Y positions.
Because Kassis et al. field does not completely contain the original field
studied by Hartwick et al. (1972, 1974), the old numbering system has been
kept. However, the better rectangular (X, Y) positions of Kassis et al.
(VI file) have been adopted as a new basis.
1998 October 23
Data from Kassis M., et al. 1997, AJ 113, 1723
- New cross-reference table,
- UBV CCD data,
- VIc CCD data,
- New rectangular X,Y positions.
The numbering system defined by the extensive catalogue of VI photometry of
Kassis et al. (4014 stars ) has been adopted for Be 39 in place of the numbering
of Kaluzny used previously. The cross-reference table contains the
cross-references with the catalogue of UBVI CCD photometry by Kassis et al.
and the numbering of Kaluzny and Richtler.
1998 October 22
Data from Barrado y Navascues D., et al. 1998, ApJ 506, 347
Data from von Hippel T., Sarajedini A. 1998, AJ 116. 1789
- Cross-reference table: column 6 added,
- VIc CCD data,
- Coordinates,
- New rectangular X,Y positions.
The 750 stars from the list of van Hippel and Sarajedini have been
numbered sequentially, because they adopted the IAU numbering system,
producing identifications like WOCS J0049562+851236 which are
difficult to use in the context of this database. The cross-reference list
may be found in the file of cross-identifications (datatype idam).
Data from Delgado A., et al. 1998, AJ 116, 1801
- Cross-reference table: column 9 added,
- UBV CCD data,
- New rectangular X,Y positions.
1998 October 21
Data from Gim M., et al. 1998, PASP (in press)
- New cross-reference table,
- VIc CCD data,
- New rectangular X,Y positions.
Data from Jahn K., et al. 1995, A&A 295, 101
The numbering system of Gim et al. (15600 stars) has been adopted in place of the numbering system
by Kustner used so far.
This new system provides a better solution to include the other CCD data sets in the database.
I am very grateful to Dr Gim for the copy of his data in advance of publication and his help in preparing the final files.
1998 October 12
Data from Tosi M., et al. 1998, MNRAS 299, 834
- Cross-reference table: column 3 added,
- UBV CCD data,
- VRIc CCD data,
- Additional rectangular X,Y positions.
