DCF computed for the Swift-UVOT W1 and Swift-XRT 2-10 keV light curves over the full campaign, between MJD 59695 (April 26, 2022) to MJD 59760 (June 30, 2022), with a time-lag binning of 2 days. The red points are the obtained DCF values and their uncertainties. The light blue and dark blue dashed lines show the 2σ and 3σ significance bands, respectively (see the main text for more details).
