1999 June 30
Data from Baume G., et al. 1999, A&AS 137, 233
- New cross-reference table,
- UBVIc CCD data,
- Additional rectangular X, Y positions.
The numbering system of Sung et al. (1998, AJ 115, 734) has been adopted and replace that
of Seggewiss used so far. It gives a good image of the cluster field, only five bright
stars from the list of Seggewiss have been added. The cross-references between the faint
stars of Sung et al. and Baume et al. remain to be done.
Data from Bosch G.L., et al. 1999, Rev. Mex. Astron. Astrofis. 35, 85

- Rectangular X, Y positions.
Data from Ann H.B., et al. 1999, J. Korean Astron. Soc. 32, 7
- UBVIc CCD data,
- Rectangular X, Y positions,
I am very grateful to Dr. Ann for providing the data in electronic form.
1999 June 22
Data from Sandrelli S., et al. 1999, Mon. Not. R. Astron. Soc. (in press)
- New cross-reference table,
- UBVIc CCD data,
- Rectangular X, Y positions,
- Coordinates.
The numbering system of Sandrelli et al. has been adopted and replace the
previous one, from Hartwick and Hesser.
The chart of Hartwick and Hesser is very dense near the center. If you
notice problems with the cross-references between the new and old numberings,
please contact me to settle the problem.
I am very grateful to Dr A. Bragaglia for providing me with a copy of the
new data for NGC 2660 in advance of publication.

Stars without V magnitudes have been attributed V = 21.5 in the X, Y file
used to plot the cluster chart.
Data from Rollestone W.R.J., Byrne P.B. 1997, Astron. Astrophys. Suppl. 126, 357
