Abstract: The validity of differing prescriptions for the reduction of data collected on inverted-geometry time-of-flight instruments has been investigated by means of Monte-Carlo ray-tracing simulations for a virtual instrument closely resembling OSIRIS at the ISIS facility and experimental measurements on the newly commissioned instrument, MARS at SINQ, PSI. In both cases, the prescription recently set out by Dorner [Bruno Dorner, J. Neutron Res. 13, 267–274 (2005)] yields the correct scattering function.
