Einstein Observatory Astrophysical Databases

compiled by: Belinda J. Wilkes (belinda@cfa.harvard.edu)

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.

Volume 3.

The Einstein Quasar Database (QSO).

    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

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.
