Module Attributes

ReferenceIntensity

Intensity distribution of the reference measurement in (z, wavelength)

IdealReferenceIntensity

math`R(Q) = 1`

NormalizationFactor

code`IdealReferenceIntensity` with added coordinate "sample"-Q

ReflectivityOverQ

Intensity histogram over momentum transfer normalized by the calibrated reference measurement.
