Description:
The Asiago Catalog of 2004 Quasi Stellar Objects (QSOs) is an updated
version of that published by Barbieri, Capaccioli and Zambon in 1975
(1975MmSAI..46..461B 1975MmSAI..46..461B).
Most of the information of these objects are taken from the literature
published before Dec. 31, 1981. Specifically, the catalog.dat file
contains names, equatorial and galactic coordinates, photometry,
redshifts, information on radio emission, variability, morphology,
presence of absorption lines, for 2004 QSOs. The indexed references
(in refs.dat) and further detailed information (in remarks.dat)
concerning absorption spectra, X-ray properties, and cross-reference
tables are also provided.

--------------------------------------------------------------------------------
Note (1): the NoteSum and u_NoteSum codes are made by summing up the
numbers corresponding to the following notes:
01: radio quiet
02: radio variability
04: optical variability
08: nebulosity or jet
16: absorption lines
32: spectral variability
(examples: NoteSum = 17 means: radio quiet with absorption lines;
NoteSum=04 and u_NoteSum=04 means: uncertain optical variability )

History:
* 28-Nov-1996: The description of this version was assumed to be
identical to the previous version VII/3 by Barbieri, Capaccioli
and Zambon (1975MmSAI..46..461B 1975MmSAI..46..461B)
* 12-May-1999: Misalignments of redshifts, resulting in redshifts
10 times too small, were corrected. The "Name" column was enlarged
to deal with long names. The QSO names were also added to the
"remarks" file.
