Abstract:
We present the first volume of the Einstein quasar database. The
database includes estimates of the X-ray count rates, fluxes, and
luminosities for 514 quasars and Seyfert 1 galaxies observed with
the Imaging Proportional Counter (IPC) aboard the Einstein Observatory.
All were previously known optically selected or radio-selected objects,
and most were targets of the X-ray observations. The X-ray properties
of the AGNs have been derived by reanalyzing the IPC data in a
systematic manner to provide a uniform database for general use by the
astronomical community. We use the database to extend earlier quasar
luminosity studies which were made using only a subset of the currently
available data. The database can be accessed on Internet via the SAO
Einstein on-line system ("Einline") and is available in ASCII format
on magnetic tape and DOS diskette.

Note (2):
1 Object included in optically selected sample for further analysis.
2 z from Marshall et al, 1984 and differs slightly from HB89.
3 Included in optically selected sample due to independent selection
in prism survey (not flagged as ``O'' or ``C'' in HB89).
4 Not included in PG ``X-ray Sample'' since it falls in declination
zone generally not observed.
5 Redshift and optical magnitude (see Table 6) from Sramek and
Weedman (1980) and differs from HB89 due to transcription error
passed through intermediate references.

1 Data used in subsequent analysis when multiple X-ray observations exist.
2 Magnitude quoted as V in HB89 or VV87, but taken as B in this paper on
basis of original references.
3 Two observations of same quasar in two different X-ray fields lead to
slightly different N 's and thereby slightly different optical extinctions
and optical luminosities.
4 VV87 computer tapes or HB89 computer tapes give magnitude update relative
to hard copy catalog.

14 Original reference quotes magnitude as R; taken as V here due to lack of
additional data.
