I have some files with the extension .uxd, obtained using Bruker D8 Discover X-ray diffractometer by someone else - I'm not an experimentalist. They represent different pole figures. Till now, I've been only dealing with simulations using discrete sets of orientations. My aim is to plot the data in order to obtain the pole figures, but projected onto different plane than the plane, where the measurements were done. 

My problem is that I don't have any idea what the *.uxd file actually contains. I would be grateful, if someone could provide me with some description of the file or suggest some software to plot pole figures on other plane (or convert the data to discrete set of orientations).
