Fluctuations of the estimated parameters as a function of the number of SNe per pixel, before (left panel sets) and after (right panel sets) noise bias removal. Each panel set consists of five panels. At each pixel we plot: a) in the first panel, the number of SNe; b) in the second panel, the value of the parameters { q₀,j₀ } respectively as the solid red and solid blue lines, with the dashed red and dashed blue lines indicating the corresponding fiducial values; c) in the third panel, the standard deviation { σ_q0,σ_j0 } respectively as solid red and solid blue lines; d) in the fourth plot, the value of H₀ as the solid black line, with the dashed black line marking the fiducial value; e) in the fifth panel, the standard deviation σ_H0 as the solid black line. Top panel sets: results from the { H₀,q₀,j₀ } estimation for one pixelation. Centre panel sets: results from the { H₀,q₀,j₀ } estimation for the average over the different pixelations. Bottom panel sets: results from the { H₀,Ω_M,Ω_Λ } estimation for Ω_κ = 1−Ω_M−Ω_Λ.
