scippneutron.conversion.graph.tof

Graphs for computing coordinates in time-of-flight neutron scattering.

See scippneutron.conversion.tof for definitions of the quantities used here. And the user guide for examples.

Functions in this module come in two categories and return graphs that

• can be used to compute a specific coordinate as identified by the function name (e.g. elastic_energy) from a given coordinate as given by the start argument. These graphs may contain more than one node if necessary.

• can be used to compute multiple coordinates, (elastic and kinematic). Their start argument works as in the other functions.
