Abstract:

The machine-readable version of the Catalog of Supplemental Stars to the Bonner Durchmusterung is a compilation of Bonner Durchmusterung stars having lower case letter designations in the original published edition of the catalog. The data include all information given in the original published edition as footnotes except for the old spectral types sometimes reported there.

Description:

The Bonner Durchmusterung catalogs (Argelander 1859-62, Kuestner 1903), declination zones +89deg. to -01deg., contain supplemental stars having lower case letter designations following the BD numbers after which they have been inserted. Many problems of identification have arisen over the years because the supplemental stars have been included in certain machine-readable catalogs without their letter designations, thus making it impossible for a computer to distinguish between a BD star and its insert(s). The need for a machine-readable version of the supplemental stars arose in connection with identifying stars in other catalogs in order to add the letter designations to them.

The initial catalog of supplemental stars was prepared from the second edition of the BD (Kuestner 1903), but proofreading and checking were accomplished by using the reprinted edition (Bonn Universitaets Sternwarte 1968) which incorporated all errata known at that time. In that way, it was possible to simultaneously derive tables of supplemental stars added, deleted, or modified for the reprinted edition.

File Summary:

Byte-by-byte Description of file: catalog.dat

Note on BDno:

BD numbers are determined by the position of the footnoted star in the original published catalog.

Note on RA* and DE*:

Equinox 1855.

Note on mag:

Magnitudes are visual and were taken directly from the published catalog.

History:

The original BD supplemental data were transferred to coded forms by K. Kress at the National Space Science Data Center (NSSDC), NASA Goddard Space Flight Center. They were also transferred to punched cards at NSSDC, and thence to a computer disk file accessible via an interactive system. The listed file was then proofread against the reprinted microversion (Bonn Universitaets Sternwarte 1968) and additions, deletions, and modifications were made to the file by W. H. Warren Jr. All letter designations are coded as lower case characters just as they appear in the original published catalog.

The order of the stars in the catalog is from north to south and increasing right ascension within each declination zone. The magnitude data must be read in character format because the words VAR and NOV occur within the field and byte 27 contains a ? in one case.

Tables 1-3 list stars that were either added, deleted, or had their designations changed in the 1968 reprinted edition of the BD. These lists enable the user to resolve differences between this catalog of supplemental stars and the 1903 edition of the published catalog, which is much more widely available than the 1968 edition.
