II/266). These quasars are grouped into variable and nonvariable populations based on measured variability confidence levels. File Summary:

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.
