+         The two detectors, A and B, have responses of 1 and 1.035,
+         respectively, meaning that their measured intensities must be divided
+         by these values to retreive their true values. These response values
+         were derived from an analysis of the diffraction patterns
+         DIFFRACTOGRAM_A and DIFFRACTOGRAM_B, both of which contain the phase
+         676A.

+         A multi-detector system was scanned through the direct beam to
+         calibrate the response of each detector to a constant-intensity
+         source. The measured intensity derived from each detector must be
+         divided by the given response to obtain the actual value. No
+         diffraction pattern or phase was involved in the derivation of the
+         response values.
