As for Fig. 14, K_p – Δv maps showing the S/N of the CCFs for all the nights combined, but with a model injected with parameters A_g = 0.5, R_p = 1.9R_J (M15). The plots show case 2 (left) and case 4 (right), with and without rotational broadening (v_{refl, mod} = 12.0 km s⁻¹ and 0.0 km s⁻¹ respectively). The cross-correlation templates match the broadening of the model in each case. The broadened model is weakly recovered with S∕N = 5.50 at K_p = 133 km s⁻¹ and Δv= 0 km s⁻¹. Without broadening the model is recovered very strongly with S∕N = 18.82 at K_p = 133 km s⁻¹ and Δv= 0 km s⁻¹. The colour bars are calibrated to peak at the highest value in each K_p–Δv map, and descend in increments of 1.0.
