Deviation measures χ_C (upper row) and χ_Η (lower) for the G2V star as function of the location of the separator τ₁ when the other two separators are fixed. Columns correspond to six different fixed values of τ₀ (values indicated at the top of each column). Each curve corresponds to a different location of the top separator τ₂. The colour of each curve indicates the location of τ₂ used to compute that curve. We do not show all the possible locations for τ₀ and τ₂ to avoid overcrowding of the plots. The grey horizontal lines show χ_C = 4% and χ_Η = 15%.
