Solution of the toy model for the TiO signal. Panel a: modeled S/N map. The yellow lines indicate the peak value at K_p = 243.0 km s⁻¹. Panel b: modeled CCF map in the stellar rest frame. The yellow lines indicate the begin and end of the secondary eclipse. We also show the continuation of the CCF trail during eclipse for a better understanding. Prior to the secondary eclipse only the terminator region at the east limb is visible to the observer, leading to a red-shift of the TiO signature (shift indicated by red arrow). After eclipse only the blue-shifted TiO signal from the terminator at the west limb is visible (shiftindicated by blue arrow).
