(a) The fitted LC with the PHOEBE model, with points representing the phase-folded data. (b) The fitted RV curve of the primary component with the PHOEBE model. (c) A mesh representation of the temperature distribution across the stellar photospheres, including a spot at phase 0.00, where the blue star is the BSS with a hotspot and the red star is the donor, respectively. (d) A mesh representation of the temperature distribution across the stellar photospheres, including a spot at phase 0.25, where the blue star is the BSS with a hotspot and the red star is the donor, respectively.
