Fig. 7.
Column response non-uniformity (CRNU; Kohley et al. 2009). Dependence of the response of the CCD detector as a function of the AC position (column) and CCD for BP (left) and RP (right) for three different wavelengths (in different colours). Some abrupt changes in neighbouring AC positions can be observed in the different CCDs due to stitch block discontinuities.
