This is the second public release of machine readable versions of Einstein Astrophysical Databases. Any news on these databases and, eventually, the databases themselves will be available through the Einstein On-line service ("einline", for details see below).
These disks contain ascii tables and text describing the tables for the following Einstein Databases:
Volume 3: The Einstein Quasar Database (QSO) The Einstein Stellar Database (STR) Volume 4: The Einstein Observation Catalog, 6th Edition (OCT)In order to aid the user in reading the tables into a database, we also provide format information for the tables (FORMAT.DOC in each subdirectory). We do not expect these to be foolproof but hope they minimize your effort. In particular, gaps in the tables may cause problems both in reading via fortran or directly accessing the ascii files. For this we apologize in advance but note that incomplete data in some cases is unavoidable.

The quasar database tables are in the subdirectory "QSO" as follows:
QSO.DOC General documentation FORMAT.DOC Summary of column names and fortran formats QSOS Object list XOBS X-ray observational data XFLUXA X-ray fluxes, energy index = 0.0 XFLUXB X-ray fluxes, energy index = 0.5 XFLUXC X-ray fluxes, energy index = 1.0 XFLUXD X-ray fluxes, energy index = 1.5 OPTICAL Optical information MISSING QSOs not processed NOTES Notes to all the tables REFS Key to references in tablesDocumentation, contained in "QSO.DOC", is reprinted from the current version of the Ap.J. Supplement draft and gives details of the X-ray analysis procedures used in determining the quantities given in this database.

The Stellar Database tables are in the subdirectory "STR" as shown in the table below. They are taken directly from the published papers listed above and labelled according to the Ap.J. volume of the paper and the table number in that paper. For each paper a ".DOC" file gives information on the contents of each table. The user should refer to the relevant paper for all scientific details.

The Einstein observation catalog and associated tables are in the subdirectory "OCT" as follows:
OCT.DOC General documentation FORMAT.DOC Summary of column names and fortran formats OBSERVNS ``The Yellow Book'' listing all observations made OBS.NAM Observer names DBREQS Databank requests CATEGS Object type
Documentation, in "OCT.DOC", gives details of the contents of the tables. For information on the Einstein Observatory and its instruments, the user is referred to the Revised User's Manual, the IPC and HRI CDROMs or the Einstein On-Line service "einline". Information on all the above can be obtained from the HEAO Newsletters or by writing to:
Einstein Catalog Office, Smithsonian Astrophysical Observatory, MS 3, 60 Garden Street, Cambridge, MA 02138
