Notes. Column (1) gives the nomenclature of the epoch in CL; Col. (2) indicates the states of CL blazar OQ 334 in various epochs; Cols. (3)–(4) give the epoch records of γ-ray in CL observed by Fermi-LAT, expressed in units MJD, year/month/day, respectively; Col. (5) indicates the photon spectral index of γ-ray and their 1-σ confidence interval; Cols. (6)–(7) give the epoch records of the X-ray and optical/UV bands observed by Swift, respectively, which * represent that there is data at this stage but not data in Swift, and ⋆ means that no corresponding data is found.
