All, Sorry, this is a little bit off topic. I could not find a thorough definition of the "Correction Factors" for absorption correction in XDS nor of the "Transmittance factors" in SADABS. We collected small molecule samples on a synchrotron beamline, processed the data with XDS and the user now needs to know the "Minimum and Maximum T" for their cif. From what I could gather, the XDS correction factors in the ABSORP.CBF are multiplied by 1000; the values are around 1 (i.e a little smaller /and/ a little larger). The cif dictionary for _exptl_absorpt_correction_T_ states "The permitted range is 0.0 -> 1.0", which clearly has to be a different definition.
Any pointers are welcome, Cheers, Jens
