This standardized document follows the rules of the Standard Description for Astronomical Catalogues. For those having to work on this catalogue using FORTRAN programs, this ReadMe file can be transformed into a f77-compliant program which reads the files making up this catalogue, in two versions: either a f77 program loading whole files into arrays, or a f77-program reading each data file line by line.
I/71 Bonner Durchmusterung Supplemental Stars (Warren+, 1980)

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.

Note on BD:
BD numbers are determined by the position of the footnoted star in the
original published catalog.
Note on RAh, RAm, RAds, DE-, DEd, DEdm:
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.
