Factors related to the detector
• The detector should be properly calibrated for spatial distortion and sensitivity of response, and should be stable. Problems with this are difficult to detect from diffraction data.
• The useful area of the detector should be calibrated or told to the integration program
– Calibration should flag defective pixels and dead regions eg between tiles
– The user should tell the integration program about shadows from the beamstop, beamstop support or cryocooler (define bad areas by circles, rectangles, arcs etc)
