Query: Monte Carlo study of the scattering error of a quartz reflective
  absorption tube   A Monte Carlo model was used to study the scattering error of an absorption
meter with a divergent light beam and a limited acceptance angle of the
receiver. Reflections at both ends of the tube were taken into account.
Calculations of the effect of varying optical properties of water, as well as
the receiver geometry, were performed. A weighting function showing the
scattering error quantitatively as a function of angle was introduced. Some
cases of the practical interests are discussed.
