In addition to absorption, multi-scan techniques also correct other slowly 
varying changes in scale factor over reciprocal space, such as those caused 
by X-ray beam inhomogeneity, goniometer imperfection, crystal decomposition, 
crystal longer than the X-ray beam cross section, absorption by the crystal 
mount etc.  These account, by and large, for much of the difference between 
estimated values of Tmin and Tmax and the _exptl_absorpt_correction_ values.
