SILICON is only useful if SENSOR_THICKNESS is also specified. For the Pilatus detector, the value to be used can usually be obtained from the frame header. For CCD detectors, a typical value of SENSOR_THICKNESS is 0.031, and the SILICON= values in the table are correct for that. | SILICON is only useful if SENSOR_THICKNESS is also specified.

Thanks to James Holton and Jason Price for coming up with the SENSOR_THICKNESS value of 0.031, and the table of SILICON= values! | Thanks to James Holton and Jason Price for coming up (by actually measuring it) with the SENSOR_THICKNESS value of 0.031, and the table of SILICON= values! The latter assumes that 40% of the 0.031 mm is air, and uses http://henke.lbl.gov/optical_constants/atten2.html and the chemical formula Gd2O2S. | ||
