If the type is "processed", the intensity Ip is corrected for background, detector response etc. as follows: Ip = (Is - Im - Ib(Tm-Ts) )/( Id*C*ds*Ts) where Is = the intensity measured with the mounted specimen Im = the intensity measured with the matrix alone Ib = the measured background intensity Id = the detector response (the above four quantities are found in _sas_scan_intensity.intensity depending on the flag given in this item. See the enumeration list for this item.) Ts = transmission coefficient of the specimen = sas_sample.specimen_transmission Tm = transmission coefficient of the matrix = _sas_sample.matrix_transmission C = concentration of the specimen = _sas_sample.specimen_concentration ds = thickness of the sample = _sas_sample.thickness The detector response is the intensity measured by the detector from a uniform scatterer (e.g. a Fe55 radioactive source for X-rays or water for neutrons).
