842this tutorial you will reduce 2D SAXS data to create 1D absolute scaled data.
843The data were collected at APS on beam line 15ID on some polymer base materials
844to be used for liquid crystal displays. The processing has several steps
845including detector calibration (i.e. determine sample-detector distance &amp;
846tilt), integration and scaling to an absolute scaled glassy carbon measurement.
847The data were collected at a wavelength of 1.0332Å with a <span class=SpellE>MarCCD</span>
