SECTION 1 INTRODUCTION

The Catalog of Galactic 0-Type St&= (Garmany, Conti and Chiosi 1982) in a compilation from the literature of all O-type stars for which spectral types, lum;tAosity classes and UBV photometry exist. Most of the entries come from Crux-Gonzalez, at al. 0974) and Humphreys (1978), with additional stars from Garrison and Kormendy (1976), Garrison, Hiltner and Schtld (1977), Garrison and Schild (1979), rei.astein, Marraco and Muzzio (1973), Feinstein, Marraco and Porte (1976), and Moffat, FitzGerald and Jackson (1979).

The catalog contains 765 stars, for each of which designation ( HD DM, etc.), spectral type, V, B-V, cluster memberships Galactic coordinates, and source references are given. in addition, the authors have included derived values of absolute visual and bolometr c magnitudes, and distances. The source reference should be consulted for additional details concernin,'d the derived quantities.

This document describes the machine-readable version of the Catalog of Galactic 0-Type Stars, as distributed by the Astronomical Data Center at Goddard Space Flight Center. It is intended to enable users to read and process the data with m minumum of guesswork, and a copy should be distributed with any machine-readable version of the catalog.

A byte-by-byte description of the contents of the Catalog of Galactic O-Type Stars is given in Table 1. The suggested format specifications apply to FOATRhN formatted read statements and can be modified depending upon individual programming and processing requirements. The format of the star ,identification field is entirely uniform within each type of identification, so the catalog can be sorted by name field and all HD, DM, 1,140C, etc, identifications will be ordered together properly. Alternate format specifications are given in parentheses.

The information contained in Table 1 is nufficient for a user to dencribe the indigenous characteristics of the data file to a computer. Not included is information easily varied from installa'cion to installation, such as block size, (physical record length) , blocking factor (number of Logical records per physical record) r total number of bl^,cker t4;je density, number of tracks, and internal coding (EBCDIC f ASCII, etc.). These parameters should always be transmitted if secondary copies of the file area supplied to other users or installations.

SECTION 4 - REMARKS, MODIFICATIONS, ACKNOWLEDGMENTS AND REFERENCES

The Catalog of Galact1 c 0-Type Stars was received on magnetic tape from Dr, C. D. Garmany of the University of Colorado on April 15, 1982. The following modifications were made to the format in order to make the star designations uniform (so that the file can be sorted by star name if desired) and to make the data records more uniform and easier to process by other users.

w 1. The H-V data were made uniform by attaching preceding zeroes where they were not present and by moving minus signs so that they always occur in byte 65.

2. Minus signs for the bolometric magnitude field were moved in order to always occur in byte 47.

3. Cluster and association membership codes ware written as -0 if not present. These were changed to blanks.

d, Signs were attached to all Galactic latitude values, uniformly in byte 68.

eGVdrCe a .a a n -C „^.^" --A t^ V%1 a;;ka a^ 4^hx 4^hs. ratrinar Of codes i21 bytes 75-78 contains digits only where reference codes are present.

6. 'Me star designation field was expanded to 18 bytes so that the identifications could be made uniform. The format was then changed by preparing a separate data set containing only the identifiers and editing all designations to contain catalog or cluster specifications in bytes 1-8, star numbers in bytes 9 - 16, and component identifications in bytes 17-18. The modified designation fields were then substituted back into the data file. A sort of the catalog by star designation will now yield a data set with all similar designations together and properly ordered.

7. The asterisk signifying a new spectral classification made by the authors, formerly appesaring at the beginning of a record, was moved to byte 119.

S. Three duplicate entries were removed after carefully checking, confirming their redu. adancy, and notifying the first author.

ACKNOWLEDGMENT

IV Appreciation is expressed to C. D. Garmany for supplying the Catalog of Calaatl c 0-Type Stars on magnetic tape with a listing and explanations, and for reviewing the modified atalog and resulting documentation.
