Ok, Lew, after a couple hours writing some really primitive
number-crunching programs, I seem now to have a valid database of 1,214
open clusters. The base work was the Lynga catalog (but that has now
changed beyond recognition), and the Ruprecht and Alter open cluster
catalogs have been brought into play as well, and the NGC2000 was used too.
The Saguaro Astronomy Club Database has been helpful for error checking,
and a couple other uses, and data from that database is 'riding piggyback'
for the time being.
More importantly, my embryonic "catalog" contains 638 cross-references for
about 300 of the open clusters, and I have another 800 or so
cross-references (mostly very obscure) to add - which should not take too
long. At this point I need help from some real experts, like Sue French and
the others on this list.
I would like to check my cross-referencing for out-of-bounds designations -
this is the next step to insuring the data retains its integrity after all
my processing. To do this, I need to know the lowest and highest numbers
represented in the catalogs listed below. I will be able to get some of
these catalogs and journal tables at the KPNO library next week, but I am
pretty certain not all will be available.
Lynga (the *old* Lynga, not the new one)
Van den Bergh
Van den Bergh - Hagan
If anyone knows (or can easily find out) the lowest and highest numbers
listed in any of these old catalogs and could e-mail the information to me,
I would greatly appreciate it! Thanks in advance.
