Hello everyone,
As per Topas wiki, argument #3 in Full_Axial_Model(filament_cv, sample_cv, detector_cv, psol_cv, ssol_cv) is "length of the detector (= receiving) slit in [mm]". In the setup I am using, there is no receiving slit, and the corresponding slot in the goniometer layout, in the software, reads "14.325 mm". This is the value I have been using so far. On the other hand, my 1D detector covers a 3.148o arc, which, from my calculations (cosine law with Rs = 250 mm) corresponds to a 10 mm chord. Would it then make more sense to use 10 mm as the third argument in the Full_Axial_Model? Thank you.
