Absolute deviation of the flux profiles from the reference for the realistic noise setting. The deviation of the estimated profiles from the reference for the different cases in the realistic noise setting: the case with optimized K matrix (first column), the case with the orthonormal K matrix (second column), the 145 case (third column), and the 367 case (right column). The profiles are for fluxes 1 through 7 from top to bottom. The number on the top right of each graph is the integral of the absolute value of each deviation profile. These numbers are summed for each case at the top of the column, next to the title.
