The primary star visible fraction η for ZTF-CBO-3, with data points color coded and vertically shifted according to period number. The best-fit model is shown as black lines, and the predicted ingress and egress phases are marked by gray bands. Observations in the first six periods generally follow the model, while observations from periods 7 to 16 exhibit greater scatter. This scatter is especially significant during ingress and egress. The occultation depth in period 16 is likely shallower than that in the other periods.
