10.10 Non-Linearity of Detector Responsivity with Flux

The linearity calibration (Section5.2.2) is only valid for certain signal ranges. Table 10.1 lists the lower and upper signal limits as given in the headers of the calibration files PxySLINR, see Section 14.8. The polynomial approximations to the non-linearity curves are not extrapolated beyond the calibrated signal ranges but are kept at the level of the boundary. In different filters different relative signal ranges may be covered. As a consequence, in some multi-filter observations unsteadiness in calibration accuracy may be introduced at the boundaries of the calibrated signal ranges.
