Merging of more than one run
After the integration of one run, one should be enabled to load another run and go through the same process of refinement. The Two hkl-files should be merged by using one scaling parameter. This scaling paramter can be determined by finding corresponding Bragg reflexes and finding a common sacling factor to match their intensities. Later in a post-refinement step, one can imagine to do a refinement of the unit cell and instrument parameters based upon all runs loaded... but this seems complicated.
