-VALUE_RANGE_FOR_TRUSTED_DETECTOR_PIXELS= masks shaded portions, and variation of its first parameter (values between 6000 and 9000) may be used to obtain the desired result (check with "XDS-Viewer BKGPIX.cbf"). UNTRUSTED_RECTANGLE= is probably the same as is available in HKL2000. UNTRUSTED_ELLIPSE= is also available. Furthermore, you could set MINIMUM_VALID_PIXEL_VALUE such that all shaded pixels are below that number, and all background values above it.
