7918 blazar-selected AGN CAZ catalog and LC

We use all-sky surveys (CRTS, ATLAS, and ZTF, abbreviated as "CAZ") to extract their optical multiband flux density on a nightly basis between 2007 and 2023, and construct as long and as high cadence light curves as possible for as many sources as attainable. We quantify the variability of the light curves and apply the Bayesian blocks algorithm to determine their flaring periods. The CAZ catalog and light curves as well as the corresponding Bayesian blocks and flaring periods are all provided in the accompanying electronic tables, enabling many analyses involving jetted-AGN variability with unprecedented sample-sizes.

Overall, we find: (1) optical flares generally have a faster rise than decay; (2) optical brightness and variability are strongly dependent on the synchrotron peak frequency; (3) flat spectrum radio quasars and BL Lac objects have comparable optical variability and flare characteristics at the same synchrotron peak frequency; and (4) optical flare times tend to decrease and amplitudes increase with increasing radio variability Doppler factor.
