Abstract:
We present variability and multiwavelength photometric information for
the 933 known quasars in the QUEST Variability Survey (Cat. II/266).
These quasars are grouped into variable and nonvariable populations
based on measured variability confidence levels.

Note (1): Identifier in catalog of 2004, Cat. II/266.
Note (2): GCL is a measure of confidence in the existence of variability above
the photometric noise ; Qi is larger for aperiodic variables.
See description in this paper.
Note (3): All luminosity densities are in units of ergs/s/Hz.
Note (4): 0.00 indicates non-detection.
