Mosaic of cross-corelation peak values obtained for a range of K₂ and T₀, and several periods between 0.131–0.136 d. The lightest (yellow colour) regions correspond to the highest cross-correlation values, normalised to the peak (marked with a pink star). Each contour is separated by 0.05 in the normalised scale. The highest cross-correlation peaks are constrained between T₀(HJD) = 2458313.40 − 2458313.42 d and K₂ = 650 − 950 km s⁻¹. For periods outside the plotted range, the contours become noisier and more distorted.
