Spectral photon distributions and calibration results for a QSO with G = 16m and z = 2 for BP (left column) and RP (right column). Top row: SPDs (black lines) and their projections onto the bases for (blue line) and (red line). Second row: simulated BP and RP observations (black dots), the result for the observational spectra from the calibration (green lines), and the results for the forward calibration (blue and red lines). Third row: coefficients resulting from the calibration (black symbols) and true coefficients (green symbols). Bottom row: normalised residuals of the coefficients. The red lines give the sample standard deviation.
