 **Coordinate space variants**
 
 The final coordinate space (`Q` in the example above) should be replaced with the appropriate space for the technique:
 - `Dspacing` for d-spacing coordinates
-- `Energy` for energy transfer
+- `EnergyTransfer` for energy transfer
 - `TwoTheta` for scattering angle
 - Multiple dimensions can be combined: `DspacingTwoTheta`
