Joint data correlation matrix between the first two even multipoles of the auto-correlation of blue galaxies and their counterpart for the blue-red cross correlation statistic in volume-limited samples. The pixels correspond to logarithmic bins spanning the scale range 5−50  h⁻¹ Mpc, the range used to obtain the final reference measurements of fσ₈ from the VIPERS data. The upper half has been box-car smoothed.
