Superposition of evolution with respect to flux of coefficients R_0,1R_1,1, and R_1,0 on the dynamical range below the threshold, as indicated by the vertical black line of Fig. 6. On this interval, all the linearly increasing correlations that are discussed in this section shows a monotonic behavior. On this CCD E2V-250, most channels exhibit a small (≈–0.003), but significant anti-correlation pedestal in R_1,0 (Y-intercept), an offset that is not seen with the others coefficients nor with the other sensors. We attribute it to the electronic chain used to collect this data, and we subtract it to the actual measurements.
