Figure 5
Division of an idealized scattering pattern, , for a given position 0 by an experimentally measured scattering pattern, I0, at the same position produces a position-specific FFC map . The position-specific FFC map has no values over any regions obscured by the beamstop, denoted by a black circle. Any asymmetric scattering in the experimental setup will appear in as an erroneous apparent response that does not correspond to an actual detector flat-field response. |
