γ-ray, half-year, time-bin light curve of 4FGL J0959.6+4606 and infrared light curves of candidate A and candidate B. Blue circles represent the γ-ray fluxes, while the red triangles are upper limits. Red bars are the corresponding TS values. The yellow region marks the epoch corresponding to high flux state of 4FGL J0959.6+4606, identified by a further monthly time-bin light curve, see Fig. 2.
