ROTAX is a new type of time-of-flight crystal-analyzer spectrometer for inelastic neutron scattering on single crystals.The instrument uses a programmable spinning analyzer to perform scans through a wide range of (Q, (o)-space. The flexibility of ROTAX has been extended by a new type of scan, the 'linear-Q' scan. We describe these scans and their preparation for a specific problem. Further we will describe the interpretation of the gathered data and focus on the transformation of the original position and time-of-flight coordinates into the relevant coordinates of reciprocal space and energy transfer. Finally, this will be demonstrated with data from phonons in copper.
