What is the instrument (Make ) you used for the reciprocal space mapping? In multi-circle diffractometry which is mainly used for this reciprocal mapping various geometries with different numbers of data acquisition modes will be used. The simplest one is the four-circle goniometer-based instrument. So each instrument will be supplied with the plotting software. So if you could explain your instrumentation technique, I can try to suggest the plotting method.

I visited another facility outside our campus. It was a Bruker D8 diffractometer. The scan was 2D reciprocal space mapping for the symmetric plane. From there, the data I brought is in .rasx format. To plot it in origin, I need it to be converted into the suitable format that I need to know.
