- Dear Sirs:
-
- Enclosed are eight single density CP/M disks containing the Yale Catalog of
- Bright Stars, revision 3, a documentation file, a program showing how to
- access the data on any star, a program which performs a simple validation
- of the catalog, and a sample bad file.
-
- The catalog was obtained from Dr. Wayne Warren of the National Space Science
- Data Center. Dr. Warren says that while the catalog is in the public domain,
- he would prefer to be the medium of distribution. The reason for this is that
- the catalog is being constantly revised as better data becomes available and
- errors are discovered. As is noted in the documentation file, he expects an
- update affecting the magnitude and color data for about 10% of the stars to
- be distributed in late 1981. The National Space Science Data Center normally
- distributes the catalog on 9 track tapes, in either IBM (EBCDIC) or ASCII
- compatible formats; they are incapable of distributing the catalog on CP/M
- disks.
-
- I am supplying the catalog to you for distribution because I feel that there
- are a large number of amateur astronomers/hobby computerists who could make
- good use of the catalog, and have no access to 9 track drives. If they did
- have access to 9 track drives, I suspect that their requests for the catalog
- and updates would quickly take up all of Dr. Warren's time. This would make
- him virtually useless to the National Space Science Data Center. I could be
- wrong, but once Pandora's Box is opened, it is very difficult to close.
-
- I would appreciate it if you would annotate a copy of this letter as to whether
- you plan to distribute the disks, and send it to Dr. Warren so that he will be
- able to refer amateur astronomers/hobby computerists to you for useable data.
-
- Very Respectfully,
- John A. Borders
