The machine version of the Yale Zone Catalogue - Integrated Version consists of nine files. Table
![[*]](/file/16884/STARBASE_ONE.ISO/catalog/yalezone/yalezone.tex/crossref.png)
gives the machine-independent file attributes. All logical
records are of fixed length, and, if the catalogue is received on magnetic
tape, it will contain blocks of fixed length except that the last block may be
short. The first file contains the basic catalogue; the second file contains
the notes to the catalogue; the next five files contain addenda for various
zones for material not included in the basic catalogue; the eighth file
contains the double star names and numbers from Aitken's New General
Catalogue of Double Stars (ADS) (Aitken 1932) for those stars in the
Washington Double Star Catalog (1984 edition) (WDS) (Worley 1984); and the
ninth file contains the variable star names for those stars included in the
General Catalogue of Variable Stars (third edition) (GCVS) (Kukarkin
et al. 1969-1970).

The information contained in the above table is sufficient for a user to
describe the indigenous characteristics of the machine-readable version of the
Yale Zone Catalogue - Integrated Version to a computer. Information easily varied from installation to
installation, such as block size (physical record length), blocking factor
(number of logical records per physical record), total number of blocks,
density, number of tracks, and character coding (ASCII, EBCDIC) for tapes, is
not included. This information should always accompany secondary copies if any
are supplied to other users or installations.
The following sections give a byte-by-byte description of the contents of each
data file.
