STOE X-Red32, absorption correction by Gaussian integration, analogous to
P. Coppens, "The Evaluation of Absorption and Extinction in Single-Crystal
Structure Analysis", published in: F. R. Ahmed (Editor), "Crystallographic
Computing", Munksgaard, Copenhagen (1970), 255 - 270. Afterwards scaling of
reflection intensities was performed within STOE LANA. J. Koziskova, F. Hahn,
